High Voltage Relay Metallized Alumina Ceramic / Ceramic Parts for Relay
1. Description:
High voltage relay metallized alumina ceramic / ceramic parts for relayis made of high purity alumina and have good flexural strength , low thermal conductivity and good thermal shock resistance.
Metallized aluminum oxide ceramic depending on the shape of the surface to be metallized, other methods such as ruling or brushing are used.Subsequently, the metallization is baked under forming gas (90% nitrogen (N2) and 5% hydrogen (H2) ). The forming gas protects the metal particles during the burn-in from oxidation. The result is a cohesive connection between metallization and ceramic.
