Perguntas frequentes

Why are boron nitride tubes suitable for high-temperature applications?

Boron nitride tubes offer high thermal conductivity, a relatively low coefficient of thermal expansion, and excellent thermal shock resistance, making them an ideal choice for certain high-temperature applications. Under appropriate inert gas protection, boron nitride ceramic tubes can operate at temperatures exceeding 3000°C.

Can boron nitride be customized for specific applications?

Yes, GORGEOUS can customize boron nitride to meet the needs of various applications. This includes length, diameter, and connector type (e.g., flat, square, threaded, etc.).

How should boron nitride tubes be stored?

Boron nitride should be stored in a clean, dry environment away from moisture and mechanical stress.

Are boron nitride tubes chemically reactive?

Boron nitride is chemically inert and not easily corroded by chemicals, making it suitable for use in corrosive environments.
