Inventor: NAKAGAWA KIYOYUKI
IPC: C04B33/13
Filed: 1994-05-19
Abstract: PURPOSE:To produce a low water absorptive lightweight tile causing no shrinkage in a molded body in firing, consisting of dense vitreous in the surface and nondensely vitreous in the inside by mixing a granular vermiculite with a clay for tile, molding and firing the obtained raw material. CONSTITUTION:The lightweight tile is obtained by mixing 10-50 pts.wt. granular vermiculite with 100 pts.wt. clay for tile and after molding the obtained raw material, firing. The bulk density of the lightweight tile is <=1.7. The sum of shrinking quantity and expanding quantity is controlled to a fixed range by mixing two raw materials in a specific ratio. In this case, the firing temp. is 800-1200 deg.C. Through the vermiculite on the surface of the fired molded material receives heat in the temp. range, air contained in the inside of itself is released outside and the vermiculite on the surface is made dense. Since the obtained tile has a dense layer on the surface, the surface hardly passes water even in contact with water.
