[China Glass Net] Crystallization is one of the characteristics of quartz glass. Quartz glass often undergoes crystallization and loses transparency when used for a long time under high temperature. So what happens when quartz glass is devitrified?

Quartz glass products that have been devitrified will crack in the devitrified layer when cooled below 275 °C. These cracks will spread to the portion where no crystallization occurs until the entire product is broken. However, if the temperature is not lowered below 300 ° C, these crystallizations are still transparent.
As long as the total number of crystallized quartz glass products is maintained above 300 ° C, the devitrified layer will not be damaged, and the product can continue to be used for a relatively long time.
The application of crystallization: quartz glass crystallization crystallized α-cristobalite, which has its harmful side, but studies have shown that the crystal structure of α-cristobalite has a supporting effect, which can enhance the high temperature deformation resistance of quartz glass.
The Ae2O3 coating utilizes this to uniformly coat a quartz tube with a layer of high-energy Ae2O3, which artificially causes a chromatographic layer at high temperatures to improve its high temperature deformation properties, allowing it to be used at a high temperature of 1300 °C.
