Abstract :
In the current research, within purification of apatite stone of Bafg investigated its using in the formulation of white glaze of Single firing of fast fired Wall Tile (Monoporosa Tile). The results of the investigations done on the purificated apatite of Bafg determined that this matter showing good thermal stability under the temperature of 1400 degress centigerate and isn’t any unfavorabale element in its compositon for using in ceramic glaze formulations exception of iron. Nevereless the problem of low Thermal Expansion Coefficient of the white glazes of Monoporosa, The Dilatometry results of the glaze containing Apatite dictated higher Thermal Expansion Coefficient. The images of SEM showed both the safe adhering of glaze to engobe and increment of amount of insoluble fine particles of zircon in the base phase of glaze that with the safe results of colourimetry was the explanatory of increment of the whitness of current glaze. Also by considering the low price of this matter, it wills reduce the final price of glaze.
