Sodium chlorate (NaClO3) is an efficient oxidising agent. Sodium chlorate from AkzoNobel is supplied to customers in crystalline form (and to some extent in liquid form) and delivered by tanker trucks, rail tank cars or tank containers containing up to 60 ton. Delivery can also be made in "big-bags" containing approximately 1 Mt.
Sodium chlorate is produced by electrolysis of a salt solution. The raw materials are sodium chloride (NaCl), water and electrical power. Sodium chlorate and hydrogen gas (H2) are formed in the process. Hydrogen can be used as a chemical raw material (for hydration, manufacturing of hydrogen peroxide etc.) or as a fuel. The solution formed is crystallised and the chlorate crystals are separated, washed and dried. The manufacturing of sodium chlorate takes place in Stockvik and Alby, Sweden, Oulu in Finland and Ambès in France.
