Abstract
A microwave heating oven comprises an inner casing or particles as an inner casing which is made of a material being heated by microwave in which a material being heated is placed; an intermediate casing made of a refractory insulator which causes less microwave loss and which covers said inner casing or particles; and means for applying the microwave from outside of the intermediate casing into the inner casing or particles. The microwave heating furnace can be used for uniformly heating the material at high temperature with small electric power. A ceramic and a porcelain can be prepared by a household microwave oven as one of the microwave heating furnaces.
