  Sodium antimonate [15593-75-6], Na2OSb2O5.1/2H2O, is a free-flowing white powder made by the oxidation of antimony trioxide in a basic medium.
  The pigmenting strength of sodium antimonate is less than antimony trioxide. It is recommended for formulations in which deep tone colours are required. Because it contains 62 wt% antimony, somewhat higher concentrations are needed to make it as effective as antimony trioxide which has 83 wt % antimony.
