| 摘要 | A process for producing a calcium silicate plate, by which both lowering in the specific gravity of the plate an increase in the strength of matrix thereof can be attained without lowering the productivity to thereby enable the production of a calcium silicate plate having a bulk specific gravity of about 0.5 to 0.8; and a calcium silicate plate produced by this process. The above process comprises shaping a starting slurry comprising 5 to 30 wt.% (in terms of solid matter) of a calcium silicate hydrate slurry, 17 to 50 wt.% of a calcareous material, 13 to 45 wt.% of a siliceous material, 2 to 8 wt.% of a fibrous material and 5 to 40 wt.% of an inorganic filler in a conventional manner and subjecting the product of shaping to hydrothermal reaction in a pressure vessel. | ||||||
