Abstract

A microwave kiln for firing ceramic material under pressure comprises a container (2), a box-shaped body (13) made of low-density alumina and rotatable inside the container (2) about a vertical axis, a firing chamber for the ceramic material, consisting of the internal cavity (14) of the box-shaped body (13), a magnetron (28) for generating microwaves and a waveguide (27) for introducing said waves inside the container (2) through an opening (24), means designed to generate a pressure greater than atmospheric pressure inside the container (2); the magnetron (28) and the waveguide (27) being movable along the opening (24) in order to produce a substantially uniform electromagnetic field inside the container (2); elements (15) made of material with a high dielectric loss factor being provided adjacent to the walls of the internal cavity (14) of the box-shaped body (13). <IMAGE>
