High Alumina Refractory Corundum Ceramic Crucible

■ Introduction：

Usually we call the crucible with alumina content over 95% a corundum crucible. Corundum ceramic crucibles are high temperature resistant containers made of corundum ceramic material. Corundum is a type of mineral that is known for its hardness, durability, and resistance to high temperatures. The high alumina corundum crucibles commonly used in the manufacturing of crucibles because it can withstand temperatures up to 1800°C without cracking or melting.

The refractory corundum ceramic crucibles are used in a variety of applications, including metallurgy, chemical analysis, and laboratory research. The alumina corundum crucibles are often used to contain samples for analysis, to melt and refine metals, and to perform high temperature reactions.

The high alumina ceramic crucibles are available in different shapes and sizes, including cylindrical, conical, and rectangular. The high alumina corundum crucible can be customized to meet specific requirements, such as size, shape, and composition. Some refractory corundum ceramic crucible are coated with a layer of glaze or enamel to improve their resistance to chemical reactions and to prevent contamination of the sample.

■ Advantages:

1. High Temperature Resistance: Corundum ceramic crucibles have a high melting point and can withstand extremely high temperatures. This makes them ideal for use in applications that require high-temperature resistance, such as metallurgy, chemical analysis, and materials science. The long time using temperature can be 1600 ℃ and short time using temperature can be 1800℃.

2. Chemical Resistance: The refractory corundum ceramic crucibles are resistant to most chemicals, including acids and alkalis. This makes them ideal for use in chemical analysis and other applications where exposure to chemicals is common.

3. Durability: The alumina corundum crucibles are highly durable and can withstand repeated use without showing signs of wear and tear. This makes them ideal for use in applications that require frequent use, such as in laboratories and manufacturing facilities.

4. Non-reactive: The high alumina ceramic crucible are non-reactive, which means they do not react with the substances that are being contained or processed in them. This makes them ideal for use in applications that require a high degree of purity, such as in the production of semiconductors and other electronic components.

5. Easy to Clean: The high alumina corundum crucible are easy to clean and maintain, which makes them ideal for use in applications that require frequent cleaning, such as in laboratories and manufacturing facilities.
