What are the high value-added applications of barite?

Barite-based polymer materials

Barite is added to the polymer as a filler, which is generally treated by ultra-fine modification process. The modified barite has good compatibility with polymer materials and can be uniformly dispersed in the matrix material to form inorganic/organic composite material. Barite has the characteristics of low cost, easy mining, wear resistance, corrosion resistance, light resistance, etc. Therefore, adding it to the rubber material can reduce the shrinkage rate of the rubber material and improve the dimensional stability and rigidity of the material. , thereby increasing the application range of rubber materials; on the other hand, adding it as a filler to rubber materials can increase the added value of barite and reduce the cost of rubber materials. In addition, barite has high density and stable chemical properties. When barite is added to paint coatings, the acid and alkali resistance and weather resistance of the coating are significantly enhanced.

Barite radiation protection material

The barium element with extremely high neutron inelastic scattering cross section can shield neutrons well, which directly promotes the application of barite cement-based materials in neutron shielding protection engineering. Using ultra-fine barite powder to make high-density barium cement, barite mortar and barite concrete building materials can replace metal lead plates to shield nuclear reactors and build radon, radon and X-ray-proof buildings for the atomic energy industry , nuclear power plants and X-ray diffraction laboratories.

Barite-based composite conductive materials

Barite is a natural white extender pigment. It uses barite as the core material and uses doped and modified SnO2 as the coating layer to make light-colored conductive pigments, which can significantly improve the added value of barite and The use value also expands the application scope of barite.

Heavy metal ion adsorption material

Dissolvable toxic metal ions have caused serious pollution to the environment in recent years, and the removal of toxic metal ions is one of the effective means to improve environmental problems. The study found that due to the structure of barite, hexavalent chromium ions interacted with the surface of barite, and the overgrowth of barite grains formed Ba(CrO4, SO4) solid, thus achieving the absorption of chromium ions, The purpose of purifying the environment is achieved.

Barite inorganic composite pigment

Titanium dioxide is a high-quality coating and occupies an important place in modern coatings. At the same time, titanium dioxide is also an important photocatalytic material. It has been found that nano-titanium dioxide can treat more than 80 kinds of toxic compounds. Due to the increasing use of titanium dioxide, it is imminent to find a replacement for it. Barite has high whiteness and stable properties.
