Potassium Iodide (KI), identified by its CAS number 7681-11-0, is an inorganic compound with a unique set of chemical and physical properties that render it highly valuable across a spectrum of industrial applications. From its role as a precursor in chemical synthesis to its utility in advanced materials, understanding KI’s characteristics is key for chemists, formulators, and production managers.

Chemically, Potassium Iodide is a salt formed from potassium and iodine. It exhibits excellent solubility in water and is known for its stability under typical storage conditions, although it can be sensitive to light and moisture, necessitating appropriate packaging by manufacturers. Its melting point of approximately 681°C and boiling point of 184°C indicate its robust nature for many high-temperature processes. The bulk density of around 1500 kg/m³ and its availability as fine particles make it easy to handle and incorporate into various formulations.

Industrially, Potassium Iodide finds applications in several key areas. Historically, it was crucial in photographic processes as a source of iodide ions. Today, it is utilized in the electrolyte of dye-sensitized solar cells, contributing to their efficiency. Furthermore, KI serves as a critical component in certain industrial cleaning agents and has roles in specialty coatings and polymers. Its use as an emergency radioprotectant for the thyroid gland highlights its significant biological relevance, though this is more in the pharmaceutical and medical sectors.

For manufacturers seeking to purchase Potassium Iodide, partnering with a reliable supplier in China offers access to high-quality material at competitive prices. The consistent availability of KI with specified purity levels, such as low heavy metal content, is crucial for the predictable performance of industrial processes. When evaluating suppliers, look for those with a proven track record in production capacity, quality assurance, and responsive customer service to ensure you can buy KI that meets your industrial needs.

The versatility and predictable behavior of Potassium Iodide make it a cornerstone chemical for many industrial advancements. By understanding its properties, businesses can better leverage this compound for innovation and production efficiency.
