product description:
It is produced by the domestic advanced chemical precipitation method. It has superior physical properties, contains less mechanical impurities, and is extremely uniform. Boiling hydrochloric acid is chemically stable and co-heated with carbon to reduce it to barium sulfide. It will not change color when it encounters hydrogen sulfide or toxic gas in the air. It is a high-quality product of similar products in China, which gives the material high density and surface finish.
