PROBLEM TO BE SOLVED: To provide a method for manufacturing an inorganic plate which is excellent in surface hardness and smoothness and high in productivity. SOLUTION: A wet inorganic plate of lamina comprising a wet mat obtained by a wet paper machine process from a slurry having a mineral fiber, an inorganic powdery body and a bonding agent as indispensable components or of which at least the front and rear layers are the wet mat, is obtained. Then, after drying the wet inorganic plate to≤20% in the percentage of a moisture content, the bonding agent is completely hardened by heating and pressurizing. COPYRIGHT: (C)2003,JPO |
