Ninety-five percent of the sodium chlorate produced in the world is used for the on-site generation of chlorine dioxide, a key bleaching agent for the environmentally-friendly ECF (elemental chlorine free) chemical pulping process. Chlorine dioxide can be produced from sodium chlorate using different reducing agents like hydrogen peroxide, sulfur dioxide, methanol, and hydrochloric acid.
Kemira is one of the largest producers of sodium chlorate in the world. The production sites in Finland, South-Eastern USA and Uruguay have manufacturing processes that are designed to produce high quality sodium chlorate, ideally suited for chlorine dioxide production. Our own patented electrolysis cell technology is the most efficient production technology available, utilizing a dependable electrolyzer combining long service life with low electricity consumption.
Sodium chlorate consumption continues to grow worldwide in the pulp and paper industry. The other key uses of sodium chlorate are as an agricultural herbicide and in uranium mining.
