Is the quartz crucible resistant to high temperatures?

Quartz crucible is a type of container commonly used in high-temperature experiments and industrial production. It is mainly used for melting metals, glass and other materials.

The quartz crucible has an extremely excellent high-temperature resistance performance. It can usually withstand temperatures above 1200 degrees Celsius. This is because its main component is high-purity silicon dioxide, which has an extremely high melting point and chemical stability. When using quartz crucibles, it is necessary to be careful to avoid rapid cooling and heating to prevent the crucibles from cracking. Meanwhile, quartz crucibles are not suitable for use in strongly alkaline melting environments because strong alkalis can corrode silica.

Quartz crucibles are mainly used in the semiconductor and photovoltaic industries. Among them, the semiconductor quartz crucible is a crucial consumable material used for growing semiconductor single-crystal silicon. It is used to hold the molten silicon liquid and ensure the growth of defect-free crystals. The size is generally 8 to 12 inches.
