Boron Nitride and Ceramic Components
 

Boron nitride and other ceramics can be hot pressed to form complex shapes, as well as be used as an additive in other materials like alloys, plastics, and even cosmetics.

Boron nitride shapes and ceramic components are critical components in applications where excellent thermal shock resistance, high electrical resistivity and chemical and corrosion resistance is required.
