Boron Nitride Ceramic BN-AlN Description

Boron nitride is a kind of advanced synthesis ceramic that was sintered at a high temperature and high pressure by BN powder. It has many excellent properties including high-temperature resistance, high thermal conductivity, easy machining, and good lubricity, making BN an outstanding material. Boron nitride ceramic BN-AlN is manufactured by a transitional plastic phase process. The relative density of the hot-pressed composite decreases as the boron nitride content increases, but 30% of the boron nitride can be obtained in more than 99% of the aluminum nitride. Though materials such as quartz are not available in high-temperature gas atmospheres, boron nitride-aluminum nitride composite ceramic gears provide reliable drive performance.

Boron Nitride Ceramic BN-AlN Advantages

• High hardness, excellent wear resistance

• High mechanical strength, high thermal conductivity

• Provide a reliable driving force for gears

Boron Nitride Ceramic BN-AlN FAQs

Q1: What is a Boron Nitride Crucible?

A1: The Boron Nitride Crucible is a high-performance container made from boron nitride and aluminum nitride. This material is known for its excellent thermal conductivity, chemical resistance, and high-temperature stability. It is commonly used in applications that involve melting or handling molten metals, ceramics, and other high-temperature processes.

Q2: Can Boron Nitride Crucibles be used with molten metals?

A2: Yes, Boron Nitride Crucibles are ideal for use with molten metals due to their non-wetting properties. They are widely used for melting non-ferrous metals such as aluminum, copper, gold, and silver. The crucibles prevent metal from sticking to the surface, facilitating easy removal and reducing contamination risks.

Q3: What sizes are available for Boron Nitride Crucibles?

A3: Boron Nitride Crucibles are available in a variety of sizes, ranging from small laboratory crucibles to large industrial crucibles. Custom sizes and designs can be produced based on your specific requirements. Standard sizes typically range from a few milliliters to several liters in capacity.
