Barium sulfate Usage And Synthesis
Chemical PropertiesBarium sulfate has its chemical formula BaSO4. It is colorless or white orthorhombic crystals with relative molecular mass of 233.4, the relative density of 4.5 (15 ºC), the melting point of 1580 ºC, and the Refractive index of 1.637. Upon being heated to 1149 ºC, it will become monoclinic crystalline when the refractive index is 1.649. It is almost insoluble in water with the solubility being 0.00022 at 18 ºC and 0.0041 at 100 ºC. It is slightly soluble in concentrated sulfuric acid and soluble in carbonate alkali metal solution in which it is converted to barium carbonate; it is insoluble in other kinds of acid or base. In nature, it is existed in the barite mineral form. Upon co-heating with carbon (pulverized coal) to 800 ºC, it is reduced to soluble barium sulfide and carbon monoxide. It has a strong ability for absorbing X-rays with X-ray being impermeable to it. Therefore, it is medically used as the agent (barium meal) for X-rays on the gut and stomach. Barium sulfate is the only non-toxic barium salts. It can be used in analysis reagents, electronics, instrumentation, metallurgy and other industries. It can also be used as a white pigment and an administrated agent upon stomach X-ray angiography; it can also used as copper flux, drilling mud weight enlarging agent and the filling agent of rubber, paper, and plastic. It is produced from the reaction between sulfuric acid and barium chloride. 
I-type barium sulfate: it is white loose powder and is odorless and tasteless.
II-type barium sulfate: it is refined from barite sulfate type minerals: barium sulfate. Calculated from the dry goods, the barium sulfate content should not be less than 97%. It is white loose powder, and is odorless and tasteless. Barium sulfate ( type and type) are both insoluble in water, organic solvent, acid o and sodium hydroxide. It contains 58.85% of barium
