Abstract

Microwave absorption in transparent ceramics or minerals containing no transition metals may be due to losses caused by ionic "rattling" in a rigid cage. Evidence for this appears in the fact that some zeolites can be melted in a matter of seconds in a standard kitchen-type microwave oven with a frequency of 2.45 GHz. This dielectric heating behavior is controlled in part by the topology of the anionic framework, location and nature of the exchange ions within the framework. Faujasite (Linde 13X) and Linde type A saturated with Na+ are the strongest absorbers. This rapid heating behavior of zeolites by microwaves opens up a new method for the processing of these important materials, and of ceramic bodies containing them in general.
