Barium Carbonate Specification

  Barium Carbonate , with CAS number of 513-77-9, can be called (Carbonic acid barium salt ; barium carbonate ; barium (ii) carbonate (gamma-type) ; witherite ; bariumcarbonate(1:1) ; bariumcarbonate(baco3) ; bariummonocarbonate ; bf1(salt) .  The applications of Barium Carbonate (CAS NO.513-77-9) are varied and include use as oil-drilling mud. Barium carbonate is sometimes employed as a neutralizing agent for sulfuric acid and, because both barium carbonate and barium sulfate are insoluble, no contaminating barium ions are introduced. The foregoing application is found in the synthetic dyestuff industry.
Barium carbonate is used in the glass industry and in the brick and clay industry. When barium carbonate is added to the clay used in making bricks, it immobilizes the calcium sulfate and prevents it from migrating to the surface of the bricks and producing a whitish suiface discoloration.
