Precipitated Barium Sulfate (Blanc Fixe)

详情

PROPERTIES
Colorless orthorhombic crystal, amorphous white powder in appearance, gravity of 4.50(15℃), good dispersion, stable chemical properties, not dissolvable in dilute acid, dilute alkali, organic solvent, or water, but dissolvable in hot concentrated sulfuric.
FEATURES AND BENEFITS
Barium sulfate is the inorganic compound with the chemical formula BaSO4. It is a white crystalline solid that is famously insoluble in water. It occurs as the mineral barite, which is the main commercial source of barium .The white opaque appearance and its high density are exploited in its main applications.
As specialized functional filler, barium sulfate from the days of good physical and chemical properties, has been widely used in powder coating, paint, printing ink, batteries, rubber, glass, cosmetics, and other relative areas .
Use 
I: Used in powder coat industry, and the barium sulfate embodies characteristics such as narrow distribution of particle diameter, thin painting membrane, even surface, and good light reflection, etc.
II: Used in industries such as dye, printing ink, rubber, storage battery, and plastic etc. They can efficiently enhance mechanical properties of project plastic, top-grade electricity insulation plastic and rubber products, they show good performance of resisting radiation.
Packaging
 Specification 25kg /sack, the inner layer is plastic membrane tried with thread; the outer layer is plastic woven sack sewed by machines.
