Sodium chlorate (NaClO₃) is a critical inorganic compound with a wide range of industrial applications, particularly in the production of chlorine dioxide (ClO₂) for pulp bleaching. As a white crystalline powder, it is known for its solubility in water and hygroscopic nature. This article provides an in-depth analysis of its properties, technical specifications, applications, and the company behind its production, HEBEI FIZA TECHNOLOGY CO., LTD..
Sodium chlorate is an inorganic compound with the chemical formula NaClO₃. It appears as a white crystalline powder and is readily soluble in water. Its hygroscopic nature means it absorbs moisture from the air, which is a key consideration for storage and handling. When heated above 300°C, sodium chlorate decomposes, releasing oxygen and leaving behind sodium chloride (NaCl). This decomposition reaction is critical in industrial processes where controlled oxygen release is required.
One of the most notable properties of sodium chlorate is its role as a precursor to chlorine dioxide (ClO₂), a powerful oxidizing agent used in various industrial applications. According to the National Institute of Standards and Technology (NIST), sodium chlorate is a key component in the production of chlorine dioxide, which is widely used in the pulp and paper industry for bleaching processes. This application accounts for approximately 95% of sodium chlorate usage globally, as highlighted in NIST's research on industrial chemical standards.
