Potassium iodide, with the chemical formula KI, is composed of potassium cations (K⁺) and iodide anions (I⁻) bonded together by ionic bonds. It usually appears as colorless or white crystals, odorless, but with a strong bitter and salty taste.
VIMATERIAL specializes in the production of high-purity potassium iodide with a purity of more than 99.9%. Our KI has low impurity content and stable performance, making it your best choice.
Melting point: 681℃
Boiling point: 1345℃
Density: 3.13g/cm³
Appearance: white to off-white crystalline powder
Solubility: Very soluble in water and ethanol.
The aqueous solution of potassium iodide gradually darkens under light and releases iodine, which makes it uniquely active in certain chemical reactions.
The preparation of KI is relatively simple, mainly achieved by the reaction of iodine and potassium hydroxide. During the preparation process, iodine dissolves in potassium hydroxide solution to form a mixture of potassium iodide and potassium iodate. Subsequently, potassium iodate is reduced to potassium iodide through evaporation, drying and mixing with carbon powder for heating, thereby obtaining a pure product. This preparation method is not only low in cost, but also mature in process and suitable for large-scale production.
Medical field: Potassium iodide is most widely and importantly used in the medical field. As an iodine supplement, KI is mainly used to prevent and treat thyroid diseases caused by iodine deficiency, such as endemic goiter (commonly known as “big neck disease”) and hyperthyroidism. In addition, potassium iodide can also be used as a preparatory drug before surgery to help shrink thyroid tissue and reduce surgical risks.
Food field: KI is also one of the commonly used additives in the food industry. This iodized salt is not only easy to store and transport, but also easy to use, becoming an effective means to prevent iodine deficiency. In addition, potassium iodide can also be used as a nutritional enhancer for certain foods to improve the nutritional value of food.
Chemical field: In the chemical field, potassium iodide, as an important raw material and intermediate, is widely used in organic synthesis, phototypesetting and other aspects. At the same time, potassium iodide can also be used to prepare other iodine-containing compounds, such as silver iodide, which have important applications in photography, analytical chemistry and other fields.
Our products implement the most stringent quality management system, and there are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.
Vacuum packaging.
1. It should be stored in a cool, ventilated, and light-proof warehouse. Protect from rain and sun during transportation.
2. Handle with care during loading and unloading, and vibration and impact are strictly prohibited. In case of fire, sand and carbon dioxide fire extinguishers can be used to put out the fire.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
