Barium metaborate Use and Manufacturing

Methods of Manufacturing

In the borax barium sulfide method, the mixture of barite and coal powder is roasted and leached with hot water in the extractor to obtain the barium sulfide material solution, which is then metered into the reactor with the borax aqueous solution and sodium silicate aqueous solution. The three materials are added. Afterwards, the reactor was sealed, heated to 110°C±5°C, stirred and reacted for 2 hours, then cooled to 70-80°C, the precipitate was centrifuged, washed with water, dried, and pulverized to obtain a finished product of barium metaborate. BaSO4+C→BaS+2CO2↑2NaOH+2BaS+Na2B4O7→2Ba(BO2)2↓+2Na2S+H2O

Uses

Modified barium metaborate is used as a primer and top coat in the coating industry. It is a new type of non-toxic anti-rust pigment. It is also used in ceramics, paper, rubber, textiles and plastics industries.
