Product Description
Natural Barium Sulfate
Natural barium sulfate, also known as barite powder, physical barium, or heavy barium, is made from natural barium sulfate ore (barite) through processes such as cleaning, polishing, and drying. Its chemical properties are very stable, insoluble in water, and resistant to acid, alkali, and non-toxic. It is widely used in the industrial field.
Precipitated Barium sulfate
Precipitated barium sulfate is a white amorphous powder with a relative density of 4.50 (15 ° C) and a melting point of 1 580 ° C. Because it has a high refractive index (1.63 ~ 1.65), it shows a whiter color and has a certain hiding power. It is almost insoluble in water, ethanol and acids, and soluble in hot sulfuric acid. It can be easily mixed with, calcium carbonate or metal nitrate. It can be reduced to with carbon at high temperatures. It is an important basic chemical raw material, the main uses: used as paint, paint, ink, plastic, rubber and battery raw materials or fillers; Surface coating agent for image printing paper and copper sheet paper; Sizing agent for textile industry; As a clarifying agent in glass products, it can play the role of defoaming and increasing luster. It can also be used as a protective wall material against radiation, and is also used in porcelain, enamel and dye industries
