Document Type and Number:
Japanese Patent JP2000510434
Kind Code:
A
Abstract:
A process for the preparation of ceramic articles having a thickness of at least about 2.5 cm, which comprises: a) selecting the ceramic composition from the group consisting of silicate material, metal oxides, nitrides and carbides, and mixtures thereof, optionally adding ceramic fibers, such as boron nitride or silicon carbide fibers, to the ceramic composition, b) autoclaving the ceramic composition to increase its hydrogen form contents, which increases the composition's microwave absorptivity, c) forming the ceramic composition into the desired shape, and d) subjecting the composition so shaped to microwave energy to internally heat and thereby dry and sinter the composition, optionally with external heat applied by means of electrical resistance or gas fired heating. Novel apparatuses for the extrusion and vibrocompaction of ceramic compositions, the drying of ceramic masses, kilns for microwave-assisted firing of the ceramic articles, cars, and a hydraulic air handling system for tunnel kilns.
