Abstract

This paper gives details of microwave firing experiments carried out with a large 17.6kW 2450 MHz microwave kiln on a range of ceramic materials.

The design of the large kiln is discussed, together with results of large batches of ceramic products. The design of successful heating experiments in terms of thermal insulation and microwave susceptors is discussed in relationship to the dielectric properties of the material to be fired.

Results are given of the fired properties from batches of products fired in the kiln, and the uniformity of the fired properties of large batches is discussed.
