Abstract: Anovel low temperature phase K3Sb0.3Y4O8. 6H2Owas synthesized hydrother-mally from K2O-Sb2O3-Y2O3-H2O system, and characterized by means of XRD, SEM, IR,TG, DTAand ICPmethods- The unit cell for the product is hexagonal with the cell parame-ters a=1.6576nm and c=1.1865 nm.The volume of the cell is calculated to be 2.8233nm3.The product was decomposed into oxides from 310℃ to 390 ℃.

Key words: Hydroxy-oxide, New low temperature phase, Hydrothermal synthesis
