COUPLED SYSTEMS DIELECTRIC - MICROWAVE TO IMPROVE THERMAL EFFECTS

A system of microwave heating of dielectric materials intimately mixed with material having poor microwave absorption properties was tested to determine the effect on such materials. The dielectric material is an important component of this system because its temperature is very rapidly increased when microwave irradiated even though some change in its crystalline structure, as shown by X-ray diffractometry, occurs a fter long exposure to microwave radiation. The dielectric transfers he at to the material with which it is intimately mixed and as a result s ubstances containing water can be raised to high temperature more rapi dly, producing steam, high pressure, weight loss or destruction of org anics.
