Effect of UHF electromagnetic irradiation (1 GHz) on the formation process of copper-calcium-phosphate glasses has been studied using X-ray phase analysis, electron microscopy and EPR spectroscopy within the temperature range 400-1200 oC. The UHF irradiation initiates polymorphic transformations of calcium phosphates and favours the destruction of copper ions associates thus causing the amorphization of sintered products. Copper associates arising in the crystalline phase define the phosphate matrix geometry in the melt in their vicinity and thus the final glass structure.
