Industrial Barium Chemicals

Barium sulfate with the chemical formula BaSO4 is a white crystalline solid. Its chemical property is solubility in concentrated sulfuric acid and poor solubility in water and other traditional solvents. The mineral barite is available in nature as a common ore of barium and is mainly barium sulfate. The premium quality Barium Sulphate Precipitated (BLANC FIXE) array finds application as a part of a catalytic mixture to selectively reduce (or hydrogenate) alkynes to cis-alkenes (the mixture consists of palladium, a carbon substrate, barium sulfate and quinoline).

Accurately composite inorganic chemical finds more application as following:

• As a filler in plastics
  
• As a component of oil well drilling fluid to increase the density
  
• Used in Episal salt
  
• Used in brake linings, anacoustic foams and powder coatings
  
• Used in root canal filling
  
• Used as a near-perfect diffuser to measure light sources in colorimeter
  
• Used as a coating for certain photographic papers in photography
  
• Used as a coating to the moulds used in metal casting in order to prevent the molten metal from bonding with the mould
  
• Used during the procedure of the soil pH test
  

In soil pH test, barium sulfate is used to precipitate out any particles (usually clay particles) which would otherwise turn into 'cloud' solution which prevent one from seeing the color of the pH indicator i.e. the result of the test.

Calcium carbonate with chemical formula CaCO3 is found in nature as rock in all parts of the world. Another source is shells of marine organisms, snails, and eggshells. It is the active ingredient in agricultural lime, and is usually the principal cause of hard water.

It is commonly used for following applications:

• Medicinally it is used as a calcium supplement or as an antacid. Its high consumption can be hazardous
  
• Calcium carbonate is used in the construction industry as a building material (e.g. marble), limestone aggregate for road building, as an ingredient of cement and as the starting material for the preparation of builder's lime by burning in a kiln
  
• It is also used in the purification of iron from iron ore in a blast furnace
  
• Calcium carbonate is used as a formation bridging and filtercake sealing agent in drilling fluids in the oil industry
  
• Used as a weighting material to increase the density of drilling fluids to control down hole pressures
  
• It is also used in growing Seacrete or Biorock.
  

The carbonate when calcined in situ gives calcium oxide which forms a slag with various impurities present, and separates from the purified iron.

Baryte (ultra white) is natural barium sulphate which is chemically BaSo4. Available in super snow white color, the chemical is a fine free flow powder. It is chemically inert to acids and alkalis. It is widely used in paint and plastic industry. Baryte is featured with accurate composition, purity, environment friendly and precise pH.
