Frequently Asked Questions
Hot pressing produces a dense boron nitride ceramic structure with consistent material properties. The appropriate BN grade should be selected according to the required temperature, mechanical, electrical, and chemical conditions.
Hexagonal boron nitride has low wettability with many molten metals, making it useful for certain molten-metal handling and high-temperature applications. Compatibility should be confirmed for the specific metal and operating conditions.
Hexagonal boron nitride is an electrically insulating ceramic while providing good thermal conductivity, making it useful where thermal transfer and electrical isolation are required simultaneously.
BN ceramic can be used in certain vacuum and high-temperature environments. Suitability depends on factors such as temperature, vacuum level, atmosphere, and the requirements of the complete assembly.
BN and alumina have different performance characteristics. BN offers excellent machinability, low friction, and low wettability with many molten metals, while alumina generally provides higher hardness and mechanical strength. The better choice depends on the specific application.
Important factors include operating temperature, atmosphere, mechanical load, electrical insulation requirements, contact materials, thermal cycling, and the required component geometry. These conditions should be evaluated together when selecting the appropriate BN material.
