The main use of barite
Application field | Main use | remarks: |
oil drilling ? | The Circulation mud weighting agent of rotary boring of oil and gas well ? | Cooling the drill bit,take away the clast cutted, lubricate drill pipe, close wall of hole,control the pressure of oil and gas, avoid the spurt of oil well |
Chemical industry | ? Used for producing BaCo3,BaCl2,BaSO4 Lithopone,Ba(OH)2,BaO and so on barium compound. | barium compound is widely used in reagent,catalytic,the refining of sugar,prevention and cure,fireproof,all kinds of fireworks,the coagulant of synthal,plastic,insectifuge,the case-hardening of steel, phosphor powder,welding agent,Oil additive and so on. |
glass | ? Deoxidizer,clarifying agent,fluxing agent | Increase the Optical temperate of glass and lustre and intensity. |
Rubber,plastics,paint | Filler,optical brighteners,weighting compound | ? |
building | The aggregate of concrete,material of paving | 1.The pipeline hidden in everglade of great pressure. 2.used in nuclear facilities replace of Pb board. 3.atomic energy factory 4. the shield of X Radiation Laboratory. 5.extend the road surface and so on |

Use | Demand index | remarks | |||
BaSO4/% | CaCO3/% | Fe2O3/% | Granularity can througth/ mesh | ? | |
Coating material | 90~95 | ? | 0.05 | <325 | The demand of whiteness is high |
Rubber filling | >98 | <0.36 | microscale | <325 | It can not contain impurity of Mn,Cu,Pb |
Normal glass | >96 | <0.1 | <0.2 | 60 | SiO2<1.5%,AI2O3<0.15% |
lithopone ? | 95~98 | ? | <1 | ? | SiO2<1%, and the more better the content of AI2O3 is |
?
Drilling grade | Density ≥4.2g/cm3, BaSO4≥92%, the content of below 200mesh ≤3%, the content of below 325mesh ≤5% |
Chemical industry grade ? | BaSO4>95%,the content of Fe2Oand SrSO4 ≤ 1%. The content of SiO2 and CaO allowed to be microscale |
Paint grade | The whiteness must be high, and it can pass through 325mesh at least. |
