Sodium chlorate (NaClO₃) is a critical inorganic compound with widespread industrial applications. As a white crystalline powder, it is known for its solubility in water and its role as a precursor in the production of chlorine dioxide (ClO₂), a key chemical in the pulp and paper industry. This article provides an in-depth analysis of sodium chlorate's properties, technical specifications, and applications, while also highlighting the expertise of HEBEI FIZA TECHNOLOGY CO., LTD., a leading manufacturer of this compound.
Sodium chlorate is an inorganic compound with the chemical formula NaClO₃. It is a white crystalline solid that readily dissolves in water and is hygroscopic, meaning it absorbs moisture from the air. When heated above 300°C, sodium chlorate decomposes, releasing oxygen and leaving behind sodium chloride (NaCl). This compound is produced in massive quantities annually, with the majority used in the bleaching of pulp to create high-brightness paper. Its versatility and reactivity make it a cornerstone in various industrial processes.
