![]() It has the function of X-ray development, which can be used in medical developing fiber and children's toys. ![]() It can be used as a protective wall material against radiation, and can be used in nuclear facilities, atomic energy plants, X-ray laboratories, etc. It can also be used as a swallowing agent (called barium meal) for fluoroscopy of intestines and stomach, cathode expansion rod of storage battery, glaze material for making ceramics and enamel, surface coating agent for printing paper and copper paper, sizing agent for textile industry, and clarifying agent for glass products, which can play the role of defoaming and increasing luster. Therefore, it is widely used in all kinds of coatings (powder coating, anticorrosive paint, ship paint, coil steel paint, container paint, automobile paint, furniture paint, exterior wall paint), electronic ink, printing ink, color paste, modified plastics (high gloss PP, ABS, PE, PS, PA, PPO, PPS, PBT, pet, flame retardant plastics, automobile plastics, household appliance shells, films, building materials plastics, etc.), optical film, lithium battery separator, and so on Transparent functional masterbatch, degradable plastics, color masterbatch, rubber elastomer, papermaking, cosmetics and other functional fillers. It is an important basic chemical raw material, main uses: Precipitated barium sulfate is a kind of environmental protection functional material because of its strong chemical inertia, good stability, acid and alkali resistance, moderate hardness, high whiteness, high gloss, and absorption of harmful X and γ rays. It is easy to make mixed crystal with potassium permanganate, calcium carbonate or metal nitrate. ![]() It can be reduced to barium sulfide and carbon dioxide with carbon at 600 ℃. It is the only non-toxic common barium salt. Due to its high refractive index (1.63-1.65), Mohs hardness 3.0, refractive index 1.64, solubility: 20 ℃: 0.00024g/100g water, can absorb harmful rays, almost insoluble in water, ethanol, organic solvents, acid and alkali, soluble in boiling heat concentrated sulfuric acid. National standard: GB / t2889-2017, relative density is 4.50 (15 ℃), melting point is 1580 ℃. The appearance of precipitated barium sulfate is white amorphous powder, chemical formula: BaSO4, molecular weight: 233.39, CAS:NO.
