Yuan Lei tells you | The use of barite powder in three major fields

Barite is barium sulfate minerals, the main component is barium sulfate (BaSO4). Produced in geothermal hydrothermal veins, often with galena, sphalerite, chalcopyrite symbiosis. It has the characteristics of high density, good filling, insoluble in water and acid, non-toxic, can absorb radiation, stable chemical and thermodynamic properties. Barite is mainly used for oil and gas drilling weighting agent, accounting for about 85% of the total consumption. Used as filler in the paint industry; Barium carbonate, barium chloride, barium sulfate, barium nitrate, etc. can be made in the chemical industry......


Below, the source of Lei Xiaobian to share the use of barite powder in three major areas:


oil well weighting agent

After grinding into fine powder, barite can be used as a weighting agent for oil well drilling mud, and the specific gravity of the mud can be increased to resist the pressure of the formation to prevent collapse and prevent formation fluid from invading the wellbore. The weight of drilling mud used in general oil and gas well drilling must be balanced with the underground oil and gas pressure to avoid accidents of well injection; in the case of high underground pressure, it is necessary to increase the mud weight. Adding barite powder to mud is an effective measure to increase the weight of mud.



Barite is an indispensable raw material for the production of barium carbonate, barium chloride, barium sulfate, lithopone, barium hydroxide, barium oxide, etc. These barium compounds are widely used in reagents, catalysts, TV glass shells, barium ferrite, sugar refining, textile, fire prevention, various fireworks, synthetic rubber coagulants, plastics, pesticides, steel surface quenching, phosphors, fluorescent lamps, welding chemicals, grease additives, water treatment, etc.



Barite used as concrete aggregate, paving materials, can extend the life of the road, can replace the lead plate for nuclear facilities, atomic energy plants, X-ray laboratories, etc., can play a very good shielding effect.

Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.

Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.
