Kandelium’s barium carbonate (BaCO3), strontium carbonate (SrCO3) and strontium nitrate play a significant part in a wide range of applications. They are important raw materials for products as varied as magnets, glasses, displays, bricks and tiles, ceramics and electronic components. Additionally, they occupy a key role in both water treatment and the production of metals, chlorides, nitrates, oxides, and more.
Barium carbonate and strontium carbonate significantly enhance the quality and properties of glass.
Clay roof tiles, facing bricks and other heavy clay ceramics use barium carbonate to prevent the formation of dry efflorescence. Barium carbonate converts soluble sulfates into insoluble barium sulfate.
With the development of new technologies in the glaze and frits industry, strontium carbonate has achieved a very important role as a raw material. It can lend frits and glazes used in multiple ceramic applications a number of special properties.
Permanent magnets using strontium ferrite – which is manufactured with strontium carbonate – are widely used in many industries. Strontium ferrite offers a high degree of chemical stability, and is completely non-toxic.
Strontium compounds are an essential raw material for the production of glass substrates used in all types of displays.
Barium titanate, which is derived from barium carbonate, is used for the production of ceramic capacitors and PTC thermistors. Ceramic plate and multi-layer capacitors are found in circuits.
In many chemical production processes, barium carbonate is used to remove sulfates. For example, it plays an important role in both chlorine-alkali electrolysis and the production of phosphoric acid.
In the production of high-purity zinc through electrolysis, strontium carbonate is used to remove lead impurities.
