Boron Nitride Composite Ceramics AlN-BN

Compositions: BN+AIN


Boron Nitride Composite Ceramics AlN-BN, Machinable Aluminum Nitride, Aluminum Nitride + Boron Nitride composite ceramic


Boron nitride material could be physically enhanced by adding some other ceramics, such as CaO (HBN), ZrO2(ZSBN), or AlN (AlN-BN), high purity boron nitride could withstand higher temperatures in an inert atmosphere than the composite/enhanced ceramics. However, the enhanced BN usually has better wear resistivity and better performance in the air.

Boron nitride composite ceramics are 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.

-High hardness, excellent wear resistance

-High mechanical strength, high thermal conductivity

-Provide a reliable driving force for gears
