Modified Precipitated Barium Sulfate
Molecular formula: BaSO4
H.S. Code: 2833270000
EINECS No.: 231-784-4
CAS No.: 7727-43-7
Description:Our modified precipitated barium sulfate is in white powder, non-toxic, melting point 1350℃,cannot be soluble in water/alcohol/acid. The products with strong chemical inertness, good stablility, Alkali-resistance, moderate hardness( Mohs:3-3.5), high glossiness and whiteness, and can absort harmful rays.The modified precipitated barium sulfate with several advantages which made by new method of precipitation is as follows:a,Main content: BaSO4(as dry per) over 98%, high purity;b,Partical size: narrow partical size, good dispersibility and liquidity. we can control the partical size in production(D50 at 0.3um min), the shape of crystalline forms of particle seems like ball. The end products with highly polished, better weather resistence ability;c,Enviromental protection: the traditional barium sulfate with odour(solium sulphide) smell which is harmful for body,but the modified products with odourless and very low heavy metal content, it is one good functional products which accord with enviromental protection.Specification:
