BARIUM SULPHATE
Barium sulphate is a naturally occurring mineral composed primarily of barium sulphate. It is usually white or colourless and is an important source of barium. The name barium sulphate comes from the Greek word 'barys', meaning 'heavy', which reflects its high density. Here is a detailed description of the properties of barium sulphate, how it is produced and its applications.That also known as barite, is a mineral that is characterised by its high density, chemical stability and opacity. It has a wide range of industrial applications, including in the oil and gas, medical, coatings and paper industries. The production of the product can be achieved through two distinct methods: the first involves the extraction of the mineral from natural ores, while the second pertains to the chemical synthesis of barium sulphate. Despite the numerous advantages of barium sulphate, it is imperative to acknowledge the potential health risks associated with its utilisation.

In nature, it exists in the form of the mineral barite. The natural mineral is called barite. Co-heated with carbon (pulverised coal) to 800°C, it is reduced to soluble of barium sulphide and carbon monoxide. It is the only non-toxic barium salt, which is used as a reagent for analysis, electronics, instrumentation and other industries. It is used in analytical reagents, electronics, instrumentation, metallurgy and other industries as a white pigment, agent for gastrointestinal X-ray radiography, copper melting agent, specific gravity increasing agent for drilling mud, and white filler for rubber, paper, and plastics. It is produced by the reaction between sulphuric acid and barium chloride.
