Sodium chlorate (Sodium Chlorate) is a critical inorganic chemical compound with the chemical formula NaClO₃. Known for its unique properties and wide-ranging applications, it plays a pivotal role in various industries, including pulp and paper manufacturing, water treatment, and chemical synthesis. This article provides an in-depth analysis of its characteristics, technical specifications, industrial applications, and the company behind its production, FIZA.
Sodium chlorate is a white crystalline powder that exhibits high solubility in water. Its hygroscopic nature means it readily absorbs moisture from the environment, necessitating careful storage conditions. One of its most notable characteristics is its thermal decomposition behavior: when heated above 300°C, it releases oxygen gas and leaves behind sodium chloride (NaCl). This property makes it a valuable precursor for generating chlorine dioxide (ClO₂), a compound widely used in industrial processes.
According to the National Institute of Standards and Technology (NIST), sodium chlorate is classified as a strong oxidizing agent, requiring strict handling protocols to prevent hazardous reactions with reducing agents or organic materials. Its chemical stability under normal conditions, combined with its reactivity under specific conditions, positions it as a key component in numerous industrial applications.

Sodium chlorate is primarily utilized in the production of chlorine dioxide (ClO₂), a powerful oxidizing agent with diverse applications. According to NIST, approximately 95% of sodium chlorate usage is dedicated to pulp bleaching in the paper industry, where it helps achieve high-brightness paper by removing lignin and other impurities. This application underscores its significance in sustainable manufacturing processes.
Beyond pulp bleaching, sodium chlorate serves as a precursor for synthesizing other chlorate compounds through salt metathesis reactions. For instance, it can be converted into potassium chlorate (KClO₃) by reacting with potassium chloride (KCl). Additionally, industrial perchlorate compounds are produced via the electrolytic oxidation of sodium chlorate solutions, highlighting its versatility in chemical synthesis.
Other notable applications include:
