About product

Barium carbonate (II), (Barium carbonate), technical - a chemical raw material with a wide range of applications in the glass industry, most often used for the production of high-quality glass and glaze. For the production of enamels, in welding processes and boiler water softening, for the production of paints and paper. In construction, used for the production of bricks and as an additive to ceramic mass.

Barium carbonate (II) with the chemical formula BaCO3, a salt of carbonic acid and barium. At room temperature, a solid, white/cream granulate, insoluble in water with a rhombic crystalline shape. At temperatures above 800 °C, it transforms into a hexagonal variety, and above 980 °C into a regular variety. During the thermal roasting process, it decomposes into barium oxide and carbon dioxide. It colors the flame intensely green. Barium carbonate is obtained by the reaction of the mineral barite with potassium carbonate under high pressure. Inhalation of barium carbonate dust can cause irritation and damage to the respiratory system. The dust also irritates the skin and eyes. When using the product, caution should be exercised and personal protective equipment should be used. Application of Barium carbonate in industry: as a product for removing sulphates in the production of glass, ceramics, glazes and enamels pyrotechnic products in welding processes for removing magnesium salts, calcium from boiler water, i.e. softening for the production of high-quality reagent; barium oxide as a filler for rubbers, paints, varnishes, paper in the production of clinker bricks, ceramics as an additive to the ceramic charge in order to remove precipitating calcium and magnesium salts, which cause cracking of finished products
