Precipitated barium sulfate is produced by chemical precipitation.
The modified barium sulfate is intended to achieve improved dispersion or other functional purposes,get on the basis of surface modification processing from the precipitation barium sulfate or barite ore.
The modified precipitated barium sulfate with several advantages which made by new method of precipitation is as follows:
a,Main content: blanc fixe (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 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.
