Abstract
PURPOSE:To obtain a multicomponent glass body with a little light transmission loss by contacting a gas of 400 deg.C or above contg. NO2 and O2 to a glass raw material mixt. contg. oxides, hydroxides, etc. followed by a glass forming reaction and cooling with an inert gas of a specified O2 partial press. CONSTITUTION:A glass raw material mixt. contg. at least one kind of oxides, hydroxides and carbonates is contacted to a gas contg. NO2 and O2 heated to 400- 800 deg.C before finishing a glass forming reaction, thereby converting impurity iron into trivalent iron by the catalytic action of the NO2. The mixt. is then heated to a predetermined temp. to finish the reaction. At this time, impurity copper is reduced to monovalent copper. The resulting glass is cooled by contact to an inert gas with an O2 partial press. of 0.01atm or below. Unlike conventional cooling in fire, iron and copper do not turned divalent, and a multicomponent glass body with a little light transmission loss for light transmission is obtd.
