Abstract

Condensed phosphates are generally prepared from their simple phosphates by heating at high temperature. The formation, structure and the morphology of the resultant condensed phosphates depend on the kind of inorganic cations as well as the conditions of preparation, temperature, heating time, and cooling rate of the melt. Condensed sodium phosphates were prepared by thermal treatment of NaH2PO4, the effect of calcinated temperature, also was studied. The products were characterized by X-ray diffraction, IR spectrum, Transmission electron microscope (TEM).The results indicate that the produced phosphate depends on the heat of calcinations. The electrical conductivity of the product was measured in range from room temperature up to 300 0C. The measurements show that the condensed phosphates tend to be a semiconductor material.
