What is Potassium Iodide Powder?
Potassium iodide Powder is a colorless cubic crystal, or granules or powder, which is slightly deliquescent in moisture. The relative density is 3.13, the melting point is 723°C, the boiling point is 1330°C, and the solubility to water is 127.5g/100g (0°C), 208g/100g (100°C), and it is very easy to dissolve. The solubility in ethanol is 4g/100g (20°C), and it is 16.5g/100g (20°C) in methanol, and it is hardly soluble in ether.
Since KI water solution is easy to dissolve iodine, it is used when preparing concentrated iodine solution. The solid extracted from the solution is potassium triiodide (KI3). It is a co-solvent for iodine and some insoluble metal iodides. It is also used as a photographic emulsifier. It is used as an expectorant, diuretic in medicine, as a preventive agent for goiter, and as a preoperative medication for hyperthyroidism. It has a broader market prospect than potassium iodate for the manufacture of rheumatism analgesic ointment with analgesic and blood-activating effects.
Potassium iodide Powder is used as an iodine supplement. Its dosage forms include tablets, mixtures and oral liquids. It is mainly used clinically for the prevention and treatment of simple goiter, thyroid crisis, and preoperative preparation for hyperthyroidism. In recent years, the clinical application of potassium iodide has continued to expand, and it has been widely used in the treatment of diseases such as dermatology, ophthalmology, joint inflammation, lead nephropathy and breast hyperplasia, and has achieved satisfactory results. Since potassium and sodium are in the same main family and have very similar properties, it is difficult to separate the impurity sodium ions in potassium iodide. The traditional purification method of potassium iodide is to recrystallize it repeatedly with water to achieve the purpose of purification. Both potassium iodide and sodium iodide have high solubility in water, so the method of recrystallization from water to purify potassium iodide has a low yield, about 80%, and the effect of removing sodium is not ideal.
Potassium Iodide Powder Use
- Combined use with antithyroid drugs may cause hypothyroidism and goiter.
- When combined with angiotensin-converting enzyme inhibitors or potassium-sparing diuretics, it is easy to cause hyperkalemia, blood potassium should be monitored.
- When combined with lithium salt, it may cause hypothyroidism and goiter.
- When combined with 131I, it will reduce the uptake of 131I by the thyroid tissue.

What is the Distinction in between Potassium Iodate and Potassium Iodide?
Currently, potassium iodate is mainly made use of for iodization in table salt in china, while potassium iodide was used in the past. It has the advantage of high iodine web content (76.4%), yet the drawback is that it is easy to oxidize, has poor security, as well as has a bitter preference. It is needed to include a stabilizer to the salt when utilizing it. The stability of potassium iodate is high, no added stabilizer is required, as well as it is unsmelling, however its iodine content is reduced (59.3%).
Potassium iodate is a lot more secure than potassium iodide during transportation and storage space. After home heating and also food preparation, the potassium iodate in the salt has actually primarily been exchanged non-oxidizing compounds. Therefore, we don’t have to bother with the oxidizing residential properties of potassium iodate, which may trigger damage to the body.
