Abstract

The invention discloses a preparation method of high temperature-resistant claret-colored glass. The method comprises the following steps: uniformly mixing 90-110 parts of silica, 3-7 parts of zirconium dioxide, 2-10 parts of phosphoric pentoxide, 4-12 parts of alumina, 1.5-5 parts of limestone, 0.5-1.2 parts of nickel oxide, 0.02-0.08 parts of cobalt oxide and 0.01-0.05 parts of cobalt sesquioxide, and melting the obtained mixture to obtain molten glass, quenching the molten glass in room temperature water, taking out the quenched glass, drying the glass, carrying out ball milling to obtain a coloring agent glass, uniformly mixing 90-110 parts of silica, 3-7 parts of zirconium dioxide, 2-10 parts of phosphoric pentoxide, 4-12 parts of alumina, 1.5-5 part of limestone and 0.5-1.2 parts of nickel oxide with the coloring agent glass, melting the obtained mixture, molding the molten mixture, carrying out heat insulation on the molded mixture, and cooling the obtained mixture to room temperature to obtain the high temperature-resistant claret-colored glass. The high temperature-resistant claret-colored glass has the advantages of excellent high temperature resistance, difficult swelling cracking under continuous high temperature insolation, uniform coloring and good light transmittance.

Description

technical field [0001] The invention belongs to the field of preparation methods of colored glass, in particular to a preparation method of high-temperature-resistant purple-red glass. Background technique [0002] With the improvement of people's living standards, colored glass has attracted more and more attention. At present, there are two production methods of colored glass: one is bulk colored glass formed by high-temperature melting; the other is colored glass formed by ion diffusion on the glass surface. The colored glass prepared by the melting method not only uses a large amount of colorant, but also needs to be melted at a higher temperature. At the same time, this method usually requires secondary color development of the product at a certain temperature to achieve the color The purpose of bright colored glass, so its preparation process is more complicated. Surface ion diffusion tinted glass was successfully developed by Bohemians in 1932. The preparation proc...
