The K0.5Na0.5NbO3 powders was prepared through ethylene glycol solvothermal method, the influence of V(EG)/V(H2O), reaction temperature and precursor concentration on phasemorphology and practical size of K0.5 Na0.5 NbO3 powders were studied. The results show that : the reaction condition of pure K0.5 Na0.5 NbO3 powders is achieved that the temperature is 230 °C, reaction time is 7 h and W(EG)/V(H2O) ≼ 3 : 2. the crystallization of powders is poor with the increase of temperature; The powders show Spherical and Cube morphology when the concentration is 6 mol/L; the powders all show cube morphology and the particle size decreased with increasing of reactant concentration, when reactant concentration is 10 mol/L and V(EG)/V(H2O) = 1 : 4, the particle size is the smallest.
