Abstract:	Microphase sn the glass system (K₂OP₂O₅)_x ? (WO₃)_1?x for x = 0.48 and 0.33 was investigated. In both systems evidence of phase separation on a scale of 100 Å to 200 Å was found. The samples stayed completely amorphous during the cooling process but the two separate phases present in the glasses could unfortunately not be identified. These results coupled with conductivity versus mole percent of WO₃ measurements suggest that the mechanism of phase separation is of the spinodal type.
