Abstract

The invention discloses a method for preparing high-temperature resistant red glass. The method includes the following steps that 90-110 parts of silicon dioxide, 3-7 parts of zirconium dioxide, 2-10 parts of phosphorus pentoxide, 4-12 parts of aluminum oxide, 1.5-5 parts of limestone, 0.5-1.2 parts of nickel oxide, 0.02-0.08 part of cuprous oxide and 0.01-0.05 part of selenium oxide are mixed to be even and melted into glass liquid, the glass liquid is subjected to water quenching in room-temperature water, taken out, dried and subjected to ball milling, and coloring agent glass is obtained; then 90-110 parts of silicon dioxide, 3-7 parts of zirconium dioxide, 2-10 parts of phosphorus pentoxide, 4-12 parts of aluminum oxide, 1.5-5 parts of limestone, 0.5-1.2 parts of nickel oxide and the coloring agent glass are mixed to be even, melted, formed, subjected to heat preservation and cooled to the room temperature, and the high-temperature resistant red glass is obtained. The high-temperature resistant red glass is excellent in high temperature resistance, not prone to expansion cracking under continuous high-temperature exposure, even in coloring and good in light transmission.

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 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 process of ...
