| Accumet Materials’ Aluminum Nitride
ceramic material offers excellent thermal conductivity for use in
semiconductor, microwave, optical, electronic and other high performance
applications. Aluminum Nitride is a cost effective, non-toxic
alternative to beryllium oxide and has a thermal conductivity nearly
eight times higher than alumina.
