Title:
TILE, METHOD FOR PRODUCING THE SAME AND TILE RAW MATERIAL
Document Type and Number:
Japanese Patent JP2006131489
Kind Code:
A
Abstract:
To provide tile exhibiting low hydration swelling in low temperature firing and freezing damage resistance and anti-water glass property in high temperature firing.
The tile has a composition of 65-75 wt.% SiO2, 7-11 wt.% Al2O3, 14-22 wt.% MgO, 1-5 wt.% CaO, ≤1 wt.% K2O, and ≤1 wt.% Na2O. The method for producing the ceramic tile is carried out by forming a raw material preparation comprising 20-40 pts.wt. agalmatolite and/or feldspar, 1-8 pts.wt. at least one kind of lime stone, slaked lime or quick lime (as CaO), 30-55 pts.wt. talc, 8-16 pts.wt. clay and 2-15 pts.wt. chamotte in the ratio per 100 pts.wt., biscuit firing the preparation, glazing and firing the formed material at 1110-1220 °C.
