Modified Barium Sulphate

Hoyonn Modified Barium Sulphate is researched and developed by the company and many local scientific research institutions. It’s produced by advanced synthetic process, special filtering technology, and surface treatment technology.

The modified barium sulphate has better mechanical performances compared to natural barium sulphate or normal precipitated barium sulphate. It has high activation, ultrafine particle size, and can effectively improve the adhesion for the final products.

Hoyonn has been in the mining industry and providing barium sulphate products for 20 years. We offer customized services to satisfy your demand.
