The difference between quartz crucible and ordinary ceramic crucible

Lianyungang professional quartz plate custom-made manufacturers will explain to you the difference between quartz crucibles and ordinary ceramic crucibles. During the high-temperature drawing process of single crystal silicon, silicon reacts with quartz crucible to increase the crystallization rate. The main differences between it and ceramic crucibles are: quartz crucible and ceramic crucible have different degrees of high temperature resistance, acid and alkali resistance. Quartz crucibles are divided into milky white and transparent. Milky white crucibles are used below 1200 degrees, and transparent crucibles are used below 1400 degrees. Ceramic crucibles are used at 1400-1600 degrees. Quartz crucibles are resistant to acids and alkalis, but not for hydrofluoric acid.

The main reasons for choosing quartz ceramics in various industries are as follows: Quartz ceramics not only have many excellent properties of quartz glass, such as: small thermal expansion coefficient, good thermal shock stability, good electrical properties, good chemical corrosion resistance, etc., but also have the characteristics of quartz glass Some excellent properties that it does not have, such as: low thermal conductivity; quartz ceramics can still be used even if crystallized, while quartz glass is devitrified and damaged when it is used; drying and firing shrinkage is small, and it is easy to form complex Shape and large products, etc.; products are more acceptable to consumers in terms of cost, price, quality, etc., and have strong competitiveness; many advantages of quartz products lead to a huge market for quartz ceramics in China, with very good development potential
