  Appearance and characters : white powder
  Melting point :1580°C , becomes crystal when 1149°C , easy to go lump when it is dried.
  Relative density :4.5 (15°C)
  Solubility: insoluble in wait and acid. Only 0.0024g/100g in water , soluble in concentrated sulfuric acid but water , alcohol ,thin acid. Becomes lump when it is dried . No poison of industry precipitated barium sulfate itself , but maybe it is toxic of soluble Barium.
