Precipitated barium sulfate

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.

Character standard : GB/T2899-1996
