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
