[en] Interaction in the systems MeCl₃-K₃TeO₃-H₂O(Me=Ga,In) has been studied at 25 deg C by the method of residual concentrations. It has been established that a ratio (n)K₂TeO₃:MeCl₃ (>=) 1.5 in the system InCl₃-K₂TeO₃-H₂O the basic indium tellurites are formed which then transfer into neutral salts. These products are X-ray-amorphous compounds. At n (>=) 2 (pH > 9) complex tellurites of the composition KMe(TeO₃)₂xnH₂O are formed in the systems under study. Complex indium and gallium tellurites are crystalline compounds; their roentgenometric data are given
