Advantages of the present invention：
Volcanic Region surface is mostly volcanic agglomerate to the next meter of deep alkalic volcanic rock in ground, is black, the volcano of aubergine
Clastic rock, and almost it is all the several centimetres to tens centimetres of basaltic foam chip and particle diameter, irregular of black or aubergine
The volcano dust do not remembered is divided into identical, finer and smoother volcano gravel Filling Cementation, and degree of consolidation is not high, and rock is loosely easy
It is broken.It is easy to gather, the work such as ball milling.By investigating, relative to the volcanic rock in other orientation, floor surface to next meter of ground depth
Alkalic volcanic rock have one it is important and obvious the characteristics of, be exactly it is generally high containing potassium in rock, other oxide contents between
Between 4.28-5.80%, average 5.28%；Sodium oxide content is between 3.25-4.52% or so；Averagely 3.63%；Oxidation
Sodium and potassium oxide sum are more than 8%, and potassium oxide content is more than sodium oxide molybdena.In this alkali basalt more regional than other
Potassium oxide content is higher by 1-4 times, and then content more regional than other is close or relatively low for sodium oxide molybdena.In a word, the fire selected by works
Mountain area surface is to be rich in alkaline potassium matter volcano with oneself uniqueness on chemical feature to the volcanic rock of the next meter of depth in ground
The chemical group and property of rock, Typical Representative-Japanese lava of so-called ' Pacific type ' the calcic rock stone of deviation is more farther, together
When, mineral matter element that the works produced are sustained out also depends on the selection of material.
First sintering of the present invention, improve base substrate hardness, reduce in experimentation because of external force and caused by it is unnecessary
Breakage, meanwhile, it is once sintered to contribute to second of sinter molding, increase the success rate burnt till.
Red Stone Ware is added in the present invention, Red Stone Ware raw material belongs to simple ore original into mud, is the higher mud ore deposit of iron-holder, and have
Excellent performance, plasticity can be improved by adding in works, improve the blank strength after shaping, the drying shrinkage phase of base substrate
To smaller, make works will not at a temperature of external environment condition season cracking.Sintering temperature is low and degree of crystallizing into is high, mud weight, husky
Property is small, and slip casting performance is good, is advantageous to works injection forming.The boccaro porosity after burning till is larger, can be just by works
Mineral matter element be fully sustained.
Inside pug is set to produce heat by alternating current in step 4 of the present invention, by moisture, pug in uneven thickness
Power frequency electric operation is carried out, effectively green compact uniform moisture is distributed in pug using autobalance effect.
The ceramic article of the present invention changes the deficiency of boccaro, and avoiding the bilgy odour of boccaro itself, (bilgy odour is mainly root
Determined according to people oneself smell), improve the eduction rate of beneficial element.The inventive method is simple, the ceramic article ring of preparation
Protect.
