How to reduce the problem of crystallization in quartz crucibles

Quartz crucibles are favored by people due to their excellent performance. Have you noticed that crystallization occurs during the use of this product? This will affect the use of crucibles, so it is necessary to reduce crystallization. Let's follow the editor to learn about methods to reduce quartz crucible crystallization.

Quartz crucible

1. Quartz crucible manufacturers should ensure that the crucible meets quality requirements from material to production.
2. We should strictly follow the process rules throughout the entire quartz crucible production process.
3. The purity of the raw materials used for crystallization should meet the production requirements. If the raw material contains a large amount of impurities, crystallization will occur during the dissolution process, especially the presence of alkali metal ions, which will lower the crystallization temperature by 200 ℃.
4. The cleaning of raw materials should meet the process requirements. Raw materials that have not undergone acid-base treatment and are not cleaned of acid-base residues can easily lead to crystallization.
5. New graphite devices, such as graphite crucibles, require high-temperature calcination before use because they contain some ash powder and other impurities.
6. The appropriate melt temperature should be selected to reduce crystallization or crystallinity.
Based on the above introduction, we know that in order to ensure the quality of quartz crucibles, it is necessary to reduce crystallization phenomena. The above points have a significant effect on reducing crystallization, and I hope they are helpful to you.
