Aluminum Nitride (AlN) Ceramics

Aluminum Nitride Description

aluminum nitride ceramicsAluminum nitride is a refractory compound ceramic material with a hexagonal wurtzite structure. Pure aluminum nitride has a blue-white color, and aluminum nitride ceramics are usually gray or white.

Common methods for preparing aluminum nitride include direct nitridation, carbothermal reduction, high-energy ball milling, high-temperature self-propagating synthesis, chemical vapor deposition, and the like.
