Quartz crucible and quartz glass crucible may seem similar in name, but in reality, there are still significant differences. These two types of silicon ingot containers have significant differences in application fields, process characteristics, and technical performance. We will explain them through the following content:
The quartz crucible is made of high-purity molten silicon micro powder. Its main chemical components are: 99.0% silicon dioxide (SiO2), 0.5% alumina (Al2O3), and 0.5% calcium oxide (CaO). The raw material used for quartz glass crucibles is a single component of high-purity quartz sand.
1. Quartz crucible
Using substrate material: quartz
Production process characteristics: Adopting ceramic production technology, its crystal phase consists of crystals and glass bodies.
Application field: Used for casting ingots of polycrystalline silicon.
2. Quartz glass crucible
Using substrate material: glass;
Production process characteristics: using glass production technology;
Application field: Used in pulling single crystals.
Quartz crucible and quartz glass crucible, two types of ingot containers, have a wide range of applications in the semiconductor and photovoltaic industries. Through a detailed comparison in the previous text, I believe everyone can also understand the specific differences between the two types of ingot containers. I hope this can better help everyone choose.
