Description
Technical field
The invention belongs to imitative blue gem-jade glass art, particularly relate to a kind of SiO
2-Sb
2O
3-Bi
2O
3System imitates blue gem-jade glass.
Background technology
The fundamental of diamond material is beautiful, durable and rare, and as a kind of artificial material, imitative gem-jade glass does not have rare characteristic, and still as a kind of substitute of gem-jade, imitative gem-jade glass must possess beautiful characteristic.So, prepare high-quality imitative gem-jade glass, must make its specific refractory power reach certain level, simultaneously gorgeous color to be arranged.
Simple glass mainly contains three kinds, is respectively crown glass, borosilicate crown glass, melting silicon-dioxide, more than the specific refractory power lower (specific refractory power RI≤1.5) of three kinds of glass.In order to improve specific refractory power, glass manufacturer adds plumbous oxide in the glass kind, and the RI of common lead glass can reach 1.60, and plumbous oxide content wherein is generally less than 40%, and their colors and gloss are dazzling, are good jewel imitations.Research shows that imitative cameo glass is a basic ingredient with high lead or medium lead crystal glass, adds various rare earth tinting materials, to reach the effect of various jewels.Lead content in the glass is high more, and RI and DISP value are big more, and hardness is more little.But acidic substance can slowly be dissolved out the lead in the lead glass.Plumbous harm to HUMAN HEALTH gets into human body generation effect through lead.Lead can get into human body through skin exposure and oral cavity, respiratory tract, and lead can be affine with multiple organ, and a plurality of systems such as nerve, blood, digestive tube, cardiovascular and cerebrovascular, urinary tract are caused damage, and has a strong impact on HUMAN HEALTH.See from development trend, replace having lead glass imperative with crown glass.More domestic enterprises adopt certain opticglass to prepare crystal ball and Crystal ornaments, and specific refractory power Nd is 1.51630～1.51671, and optical property is not as lead glass, but cost is lower than lead glass.
In present simple glass or imitative cameo glass, often through add Gao Tai etc. with improve glass such as optical properties such as specific refractory poweres, but the content of titanium too much can influence the transparency of host glass itself, thereby the effect of jewel is imitated in influence.In addition, in present simple glass or imitative cameo glass, often add content and be no more than 1% Sb
2O
3(in the quality % of oxide compound benchmark) carries out deaeration to glass melting.Form through the adjustment prescription in the present invention, add content and surpass 20% Sb
2O
3(in the weight % of oxide compound benchmark) not only can improve the specific refractory power of glass to a certain extent, simultaneously, owing to after having reduced the usage quantity of materials such as titanium, niobium, increased the transparency of host glass, improved the effect of the imitative gem-jade of glass greatly.So far do not see also that relevant meaning is with SiO
2-Sb
2O
3-Bi
2O
3That system prepares under the situation of high antimony content is unleaded, the report aspect the imitative sapphire of high refractive index.

(2) above-mentioned raw materials is mixed and ball milling 3-5 hour, so that the powder thorough mixing;
(3) with the powder that mixes, put into quartz crucible, and 1450 ℃ of fusings down, clarification is after the homogenizing; Treat to pour into a mould after furnace temperature is cooled to proper temperature, put into then and obtain product of the present invention after lehre is annealed.
Inventive principle of the present invention:
The compositing range of forming each composition of opticglass of the present invention is described below.The content of each composition is all represented with weight % in this specification sheets.In addition, it all is the composition that the weight % with the oxide compound benchmark representes that the glass represented with % in the present specification is formed.Wherein, " oxide compound benchmark " is meant; Suppose as the raw material of glass moity of the present invention and the oxide compound that uses, nitrate salt etc. all are decomposed when fusion and when changing into oxide compound; Quality summation with this generation oxide compound is 100 quality %, representes the composition of contained each composition in the glass.
In the glass of the invention described above, B
2O
3Composition is as the indispensable composition of network former, has to improve glass increased devitrification resistance and the effect that improves viscosity in the liquidus temperature.But, if B
2O
3Amount anti-at least increased devitrification resistance insufficient, be difficult to obtain targeted refractive index at most if cross.Therefore, can contain lower limit and be preferably 2%, the upper limit is preferably 10%, most preferably is 5% B
2O
3
SiO
2Also be that glass generates body, a spot of interpolation can be kept the chemicalstability of glass and the proper viscosity when improving, but SiO
2Specific refractory power for improving glass is unhelpful.So in the present invention, the use SiO that tries one's best few
2
Rn
2O (Rn representes to be selected from more than one among Li, Na, the K) composition is to significantly reducing the effective constituent of vitrifying point (Tg) and promotion hybrid glass raw materials melt.But, Rn
2The introducing of O is unprofitable to the raising of glass refraction, and can cause the decline of the anti-property of glass when too much using.Selected Rn in this test
2Be limited to 20% on the O.Li wherein
2O is no more than 5%, Na
2O and K
2O respectively is no more than 10%.
RO (R representes to be selected from more than one among Ca, Ba, the Sr) composition can improve the chemicalstability of glass, and fluxing action is arranged, but its content is higher than at 10% o'clock, and the tendency of analysing of glass increases, and specific refractory power is difficult to reach the requirement of invention.Therefore, in order to be easy to keep the stability of glass, RO adds as optional components.The upper limit of content elects 10% as.
TiO
2Composition and/or Nb
2O
5Composition is to improving glass refraction, help polymolecularity, improving the increased devitrification resistance and the effective composition of chemical durability of glass, if but TiO
2And/or Nb
20
5Amount glass melting property at most with stability the tendency of easy deterioration is arranged on the contrary.Therefore, to close quantifier, can contain the TiO of 0-35%
2And/or the Nb of 0-50%
20
5TiO
2Composition is to improving glass refraction, help polymolecularity, reducing the effective composition of liquidus temperature, if but TiO
2Amount too much has the tendency that increases the glass increased devitrification resistance on the contrary.Therefore, in glass, add the fashionable upper limit and should not surpass 15%Nb
20
5Composition is to improving glass refraction, help polymolecularity, improving the effective composition of increased devitrification resistance of glass, if but Nb
20
5Measuring glass melting property at most has the tendency of deterioration.Therefore, when adding in the glass, the upper limit should not surpass 20%.Though adding separately in the glass, above-mentioned two kinds of compositions also can reach the object of the invention, because both excessive tendencies, particularly TiO that increase glass increased devitrification resistance is all arranged
2So,, the present invention selects both simultaneously for use, and keeps TiO
2+ Nb
2O
5Content be no more than 15%, to reach anti-increased devitrification resistance and the double effects that improves specific refractory power.
Bi
2O
3Be the composition that improves glass refraction and chromatic dispersion, and can reduce the softening temperature of glass, but its usage quantity can cause that the crystallization of glass worsens when too much, paintedly significantly increase, the proportion rising, so its content is 0-20%.
Sb
2O
3Can keep the specific refractory power of glass to a great extent, high-content uses Sb
2O
3, be great innovation part of the present invention, its upper content limit can be decided to be 65%.
Beneficial effect
(1) environmentally harmful material such as not leaded, the arsenic of imitative blue gem-jade glass of the present invention, environmental friendliness, specific refractory power high (greater than 1.65) has the good optical performance;
(2) glass of producing with the inventive method has imitative sapphire good effectiveness.
