1. Brief introduction
Barite, as an important non-metallic raw mineral, is mainly composed of barium sulfate (BaSO4). With characteristics of being insoluble in water, high density and good filling capacity, barite has high application value in many fields.
2. Specific application
✱ Weighting agent for oil drilling mud
Barite plays a vital role in oil drilling. As the main weighting agent of drilling mud, barite can significantly increase the density of mud. It can also help cool the drill bit, strengthen the well wall and control oil and gas pressure, these are all helpful to prevent blowout accidents. According to statistics, the use of barite as weighting agent accounts for 85% to 90% of its total consumption. This application ensures the safety and efficiency of oil drilling, meanwhile establishes the important position of barite in global energy industry.
✱ Production of barium Compound
Barite is an important raw material for producing a variety of barium compounds, such as barium oxide, barium carbonate, barium chloride and barium nitrate. These barium compounds are widely used in fields of chemical reagent, catalyst, sugar refining, textiles, fireproof materials, fireworks manufacturing and coagulants for synthetic rubber. For example, barium carbonate is an important raw material for optical glass, it can increase the refractive index of glass and improve its optical properties; Barium chloride is used as an agricultural pesticide; And barium nitrate plays an important role in fireworks and glass industries.
✱ Nuclear radiation protection material
Barium in barite has an extremely high neutron inelastic scattering cross section, it can effectively shield neutrons, so it is widely used in nuclear radiation protection project. High-density barium cement, barite mortar and barite concrete building material made of ultra-fine barite powder can somewhat replace metal lead plates, to shield nuclear reactor and build radon-proof and X-ray-proof buildings. This can provide safety protection for atomic energy industry, nuclear power plants and X-ray laboratories.
✱ Composite conductive material
Through doping modification, barite can be used as core material to make light-colored conductive pigments, this can significantly improve the added value of pigment. This pigment not only has ideal appearance color and conductivity, but also can be used to produce conductive coatings, antistatic coatings, conductive plastics and conductive rubber, it provides new options of material for electronics and electrical appliance industries.
✱ High temperature resistant and friction resistant materials
Combining or compounding barite with compounded with raw minerals of different chemical compositions, structures, can produce composite alloy deoxidizercan. The composite alloy deoxidizer is of high temperature resistant and friction resistant. This material has important application in high-temperature industries, such as steel-making, it can significantly improve the quality and performance of steel.
✱ Alternative coating of titanium dioxide
With properties of high whiteness and stability, barite can be used as core material to composite with titanium dioxide. This composition can effectively solve the problem of agglomeration of titanium dioxide, and improve its photocatalytic property. Moreover, barite can also be used directly as coating to replace titanium dioxide, this provides a new option for coatings industry.
✱ Medical contrast agent
In medical field, barite or its derivatives can be used to produce contrast agents in digestive system, this can help doctors to make more accurate judgement and improve the medical standards.
3. Summary
The application prospect of barite is very broad. With the advancement of technology and the improvement of environmental awareness, the application scope of barite will be further expanded in future.
In practical application, in order to meet the requirements for particle size in different application fields, barite needs to be ground and classified. Grinding and classifying equipment plays an important role in practical application of barite, for example: ball mill and air classifier.
