| Abstract: | We have studied crystallization behavior in M21O-P2O5-V2O5-CaO and M21O-P2O5-V2O5-CaO-YF3 flux systems (M1= Na, K) for discrete ratios P/V = 0.04-0.14 and M1/(P+V) = 0.7, 1.0, 1.2, 1.4, w(CaO) = w(YF3) = 5 wt.%. We established the conditions for the formation of phosphate vanadates
based on apatite, whitlockite, NaCaPO4, KCaY(PO4)2, and YPO4 structural types. |
