Composite Ceramic BN-AlN Description

Boron Nitride Composite Ceramic BN-AlNBoron Nitride is a kind of advanced synthesis ceramic which was sintered in the 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, makeing BN an outstanding material.

Boron nitride composite 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.

•  High hardness, excellent wear resistance

•  High mechanical strength, high thermal conductivity

•  Provide a reliable driving force for gears
