    Barium Sulphate | Applications and Specifications

    Barium sulphide is treated with sulphuric acid or sulphate salts to obtain barium sulphate of high purity. The barium sulphate produced with this method is known as “blanc fixe” which is “permanent white” in French. In the laboratory, barium sulphate is produced from combining solutions containing barium ions and sulphate salts.

    Since barium sulphate is highly insoluble in water only by carbothermal reduction of barite (barium sulphate) it changes into water soluble barium sulphide. Use of sodium nitrate as a catalyst to enhance the percentage of reduced barium sulphide is quite encouraging. It is a simple industrial method and affects the economy of the industries.

    Apr 25, 2017 Baryte is turned into barium sulphate by the process of carbothermal reaction, which means that it is heated with coke. For highly pure barium sulphate to be produced barium sulfide is treated with sulfuric acid or salts. Barium carbonate is made commercially and in labs by treating barium sulfide with sodium carbonate using the soda ash method.

    Reduction of barium sulphate (BaSO 4) to barium sulphide (BaS) is an important step in producing barium chemicals from barite (natural barium sulfate mineral). Barite ore is a basic starting material for manufacturing a variety of barium chemicals such as BaCO 3, Ba(OH)2, Ba(NO 3)2, Ba(HS)2, BaO (Alizahed et al. 2010).

    Abstract Barium carbonate is an important industrial material. Conventional method of BaCO 3 preparation is based on high-temperature reduction of barite (natural barium sulfate) with coal, which produces a great amount of CO 2 (greenhouse gas). This research offers a clean method for BaCO 3 production with methane as the reducing agent, which decreases the CO 2 emission considerably (up …
