Abstract
Inorganic raw materials are heated and pressed in a kiln to produce a porous ceramic panel. The foaming body is first-pressed in a foaming step, and after the foaming step the first-pressed foamed body is second-pressed, in order to obtain superior dimensional accuracy and surface smoothness. The panels are applicable, for instance, to interior or exterior materials of various kinds of buildings such as prefabricated houses and shops.
