Sodium chlorate is an inorganic compound with the chemical formula NaClO3. This white crystalline powder is highly soluble in water and exhibits hygroscopic properties, meaning it readily absorbs moisture from the environment. Its thermal decomposition above 300°C releases oxygen and leaves behind sodium chloride, making it a critical component in various industrial processes. With annual production reaching several hundred million tons, sodium chlorate is predominantly used in the pulp and paper industry for bleaching to achieve high-brightness paper. This article explores the features, advantages, technical specifications, applications, and the company behind this essential chemical.
Sodium chlorate is renowned for its unique physical and chemical properties. As a white crystalline solid, it is hygroscopic, requiring careful storage to prevent moisture absorption. Its high solubility in water makes it ideal for aqueous solutions used in industrial applications. Additionally, sodium chlorate acts as a strong oxidizing agent, which is crucial for its role in generating chlorine dioxide (ClO2), a key chemical in pulp bleaching. The compound’s stability under normal conditions ensures safe handling and transportation, while its reactivity at elevated temperatures allows for controlled decomposition when needed.
The purity of sodium chlorate is a critical factor in its performance. High-purity grades, such as the 99% purity offered by FIZA, minimize impurities that could interfere with industrial processes. This ensures consistent results in applications like paper production, where even trace contaminants can affect the final product’s quality.

Sodium chlorate is primarily used in the production of chlorine dioxide (ClO2), which is essential for bleaching pulp in the paper industry. This process accounts for approximately 95% of sodium chlorate’s industrial use. The remaining 5% is utilized in the synthesis of other chlorate compounds through salt metathesis with corresponding chlorides. Additionally, sodium chlorate serves as a precursor for perchlorate compounds, which are produced via electrolysis of sodium chlorate solutions.
Beyond the paper industry, sodium chlorate finds applications in water treatment, where it is used to disinfect and purify water. It is also employed in the production of herbicides and other agricultural chemicals. The versatility of sodium chlorate makes it an indispensable component in various sectors, from manufacturing to environmental protection.
