Barite is a non-metallic mineral product with barium sulfate (BaSO4) as the main component. Pure barite is white and shiny. It is often gray, light red, light yellow, etc. due to the influence of impurities and mixtures. Fairly good barite can also appear as transparent crystals. Barite sulphate mineral. The composition is BaSO4. Barium-containing minerals widely distributed in nature. Barium can be replaced by strontium isomorphism to form lapis lazuli; partially replaced by lead to form Beitou stone barite is an important non-metallic mineral raw material, which has a wide range of industrial applications.

Anti-ray cement, mortar and concrete, using barite to absorb X-rays, barium cement, barite mortar, and barite concrete are made of barite to replace metal lead plates to shield nuclear reactors and build scientific research, X-ray-resistant buildings in hospitals. Barium cement is made of barite and clay as the main raw materials. After sintering, clinker with dibarium silicate as the main mineral is added, and an appropriate amount of gypsum is added and ground together. The specific gravity is higher than that of ordinary portland cement, which can reach 4.7 ～ 5.2. The strength number is 325 ～ 425. Due to the large specific gravity of barium cement, it can be formulated with heavy aggregates (such as barite) to make uniform and dense X-ray-resistant concrete.

Barite mortar is a mortar with a large bulk density and a barrier effect against X-rays. Generally, Portland cement with low heat of hydration is required. Commonly used cement: barite powder: barite sand: coarse sand. The ratio is 1: 0.25: 2.5: 1. Barite concrete is a kind of concrete with large bulk density and shielding ability against X-rays. Generally, cementitious materials are Portland cement with low hydration heat or high-alumina cement, barium cement, strontium cement and other special cements. Portland cement is the most widely used. For the barite of anti-ray mortar and concrete, the content of BaSO4 should not be less than 80%, and the impurities such as gypsum, pyrite, sulfide and sulfate should not exceed 7%.

Barite is chemically stable, insoluble in water and hydrochloric acid, and non-magnetic and toxic. Guizhou barite crystals belong to orthorhombic (orthorhombic) sulphate minerals. Often thick plate-like or columnar crystals, mostly dense block or plate-like, granular aggregates. When pure, it is colorless and transparent. When it contains impurities, it is dyed into various colors. The streaks are white. The glass is shiny and transparent to translucent. The three groups are completely cleaved, and the included angle is equal to or close to 90 °. Mohs hardness is 3-3.5, specific gravity is 4.0-4.6. Identification characteristics: plate-like crystals, small hardness, complete cleavage near the right-angle intersection, high density, no foaming in the presence of hydrochloric acid, and distinguish it from similar calcite. Barite is a non-metallic mineral product with barium sulfate (BaSO4) as the main component. Pure barite is white and shiny. It is usually gray, light red, light yellow, etc. due to the influence of impurities and mixtures. Crystallization Fairly good barite can also appear as transparent crystals.
