A WHITE SINTERED GLASS-CERAMIC TILE AND METHOD OF PREPARING THE SAME

摘要

The invention provides a white sintered glass-ceramic tile and a method for preparing the white sintered glass-ceramic tile. The white sintered glass-ceramic tile is a single fired tile with a glazed glass-ceramic layer and a porous glass-ceramic layer, wherein each layer is prepared using same starting raw materials. The method includes milling the starting raw materials to obtain a homogenous mixture. The homogenous mixture is melted and poured in water to obtain glass frits. The glass frits are milled and thereafter, sieved to obtain glass frit powder with particle size of below 100 micron (µm). A mixture of the glass frit powder and one or more foaming agents is cold pressed to form a porous glass-ceramic layer. Thereafter, the glass frit powder is deposited on the porous glass-ceramic layer to obtain a glazed glass-ceramic layer. Finally, both the layers are fired together.
