Tradeasia International as a global barium carbonate supplier provides you with barium carbonate for your market and industry solution. Get barium carbonate in different grades, quantities, and packaging right now
An inorganic chemical with a white powder appearance, barium carbonate is sometimes called Pigment White 10. Barium carbonate may be available as ultra-fine powder, fine powder, or coarse powder. Due to its low solubility in water, barium carbonate is used in preparing glass, ceramics, cement, and other relevant materials.
Specific in ceramics, barium carbonate is commonly used as a raw material with iron oxide to produce barium ferrite, which has a high magnetic coercivity and high stability, thus is suitable to be used in many components with permanent magnets. We provide barium carbonate in different grades, quantities, and packaging for your market and industry solution.
Barium carbonate is obtained from the reaction of barium sulphide with sodium carbonate or carbon dioxide. To obtain barium carbonate, some industries use two commonly used methods: the soda ash method and the carbonation method. In the soda ash method, barium sulphide is reacted with dissolved sodium carbonate, while in the carbonation method, carbon dioxide is supplied to barium sulphide in a reactor.
Barium sulphide as the raw material for barium carbonate manufacturing is obtained through the crushing and milling process of barite ore. After the thermal and grinding treatment of barite ore, barium sulphide is leached from the ground melt.
Pulp and Paper
Barium carbonate provides whiteness as a white pigment; hence, used in paper coating for white paper manufacturing. The optical and tactile characteristics such as whiteness, glosses, and smoothness of the papers are improved through the addition of barium carbonate. .
Glass and Ceramic
Barium carbonate has been used as the raw material in high-fire glazes. Since it can increase luster and refractive index, barium carbonate often used to manufacture matt glazes, clay bricks, and ceramic tiles to improve their aesthetic value.
The Sulphate-rich water issue can be solved by adding precipitating agents such as barium carbonate. By precipitating mechanism, the amount of sulphate in water can be reduced by generating the precipitated barium sulphate from barium carbonate addition and further separating the precipitated species.
