Abstract

Ceramics based on aluminum nitride is a perspective material used in electronics as housings and substrates for electronic chips due to its unique combination of high thermal conductivity and high dielectrical properties. More than 90% of aluminum nitride ceramics market are presented by metallized ceramic products, therefore it is necessary to develop metallization pastes intended for ceramics based on aluminum nitride. At the moment the process of aluminum nitride metallization is poorly understood. One of the most effective ways of ceramics metallization is usage glass as binding additive in metallization pastes. In this article are presented results of research of different glass compositions for possibility of their application in metallization pastes intended for ceramics based on aluminum nitride. It includes research of contact angle of aluminum nitride with glasses of different compositions at different temperatures and different roughness of ceramics.
