Calcium Iodate Monohydrate

Calcium Iodate Manufacturer in India

Calcium Iodate is an inorganic chemical compound made up of calcium and an Iodine derivative – Iodate. It is slightly soluble in water and its iodine content is 62%. They are available in two forms namely – hexahydrate and anhydrous, both of them occurring naturally as colorless salts. The hexahydrate form (Ca(IO3)2(H2O)) is known as bruggenite and the anhydrous form (Ca(IO3)2) is known as lautarite. Lautarite is considered the most significant source of Iodine. Calcium Iodate is being prepared, provided and exported by one of the best calcium iodate manufacturer in India.

Production and preparation

Sodium iodide is reduced from lautarite ores’ aqueous extracts by using sodium bisulphate as a reducing agent. In order to produce calcium iodate, calcium iodide is oxidised anodically. Another way of producing calcium iodate is by dissolving iodine in a hot solution of lime and then passing chlorine through it.


Calcium iodate is used majorly in poultry and agriculture industry as a component in animal food products such as chicken feed in order to correct and prevent iodine deficiency in animals. It is also used to prevent certain diseases in animals. It is also used in pharmaceutical industry in the manufacture process of antiseptics, disinfectants and deodorants.
