the barite powder , usually with the whiteness is abt 70% , and 325 mesh, specific gravity is 4.2 it can be widely use in oil drilling , rubber and auto brake pads .
PHYSICAL PROPERTIES | CHEMICAL PROPERTIES (BY WEIGHT) | ||
Appearance | Fine White Powder | Content of BaSO4 | ≥90% |
Specific Gravity | 4.1-4.2 g/cm³ | SiO2 | ≤2.5% |
Particle size | 45um-75um | Al2O3 | ≤ 0.5 % |
Water Soluble | ≤ 0.1 % | CaCO3 | ≤ 2% |
Moisture | ≤ 1% | Polymerization | No Polymerization |
Application | Use as materials of oil-drilling mud fluid as weighting additives to increase the mud weight without increasing the solid content. The mineral has high specific gravity to be use for increasing mud density in many types of drilling fluid systems, etc. | ||
