Preparation of precipitates for obtaining Zn_2Sn0_4 is examined by the homogeneous precipitation method in which SnCl_4, ZnCl_2 and (CH_2) _6N_4 are used. The precipitation becomes difficult with increasing concentration of SnCl_4 and decreasing ratio of (CH_2) _6N_4 to SnCl_4. The homogeneous precipitation method becomes difficult to apply with increasing ratios of ZnCl_2 to SnCl_4 and of (CH_2) _6N_4 to SnCl_4. The amount of zinc contained in the obtained precipitate increases with increasing ratios of ZnCl_2 to SnCl_4 and of (CH_2) _6N_4 to SnCl_4. The precipitate obtained is Sn0_2 with poor crystallinity and contains zinc. Heating at 700℃ resulted in the mixture of ZnO, Sn0_2 and Zn_2Sn0_4. The amount of zinc in the calcined material which dissolves into 2N HCl solution increases with increasing calcining temperature.
