Product details

DMCERA® Boron Nitride Composite

Boron niitride combines excellent thermal stability,chemical stability and electrical insulation.It also has high thermal conductivity, high resistivity and outstanding machinability performance. Boron nitirde composite is produced by BN and other materials (SiC,Si3N4,ZrO2,AIN,etc). Compared with pure BN ceramic,the composite ceramic has higher comprehensive performance and wider application. It is widely used in thermal protection materials, high temperature wave transmission materials, high performance aviation friction materials, and anti-oxidation coating materials fields.

Advantages:

● Easy to machine.

● Long service life.

● High toughness.

● High mechanical strength.

● Good wear resistance.

● Excellent thermal shock resistance.

Applications:

● Thermal insulation composites

● Electromagnetic windows

● Hypersonic missile radomes

● Break ring and side dam for continuous casting

● Nozzles for metal atomizing and powder metal atomization
