SYNTHESIS OF FELDSPAR SUBSTITUTES VIA UTILIZATION OF LOCAL MATERIALS

Abstract

Four varieties of sodium feldspar substitutes have been prepared. Different percentages of kaolin, silica and sodium salts are milled, mixed and submitted to heat treatment. The reacted powders are then grinded and tested by x-ray diffraction. The results show the existence of feldspar phase. The densities were measured and show close agreement to the reported values. The final result is establishing a technological root for the synthesis of feldspar substitute utilizing local materials.
