Sintering low dielectric loss material by microwave heating - using preheat material to increase dielectric loss

摘要

A process for sintering high melting pt. inorganic materials with low dielectric losses, by microwave heating, employs a preheat material which has high purity, is located outside the material to be sintered, exhibits good conversion of microwave radiation into heat and reacts completely to inert products. The preheat material preheats the inorganic material to increase its dielectric loss and allow it to be heated to the sintering temp. by microwave absorption. USE/ADVANTAGE - In the microwave firing of materials such as ceramics, glass and the like. The preheat material combusts to an inert product and permits variable heat up rates and max. temp. values.
