What is Potassium Iodide?
Molecular Formula (Potassium Iodide): KI
Molecular Weight: 166.003 g/mol
Chemical Name: Potassium Iodide
CAS Number: 7681-11-0
It is a metal halide compound consisting of a mineral element like Potassium and a halogen element like Iodine. It has expectorant and protective properties.
It belongs to the class of medications defined as Anti-Thyroid drugs. Its mechanism of action is to prevent radioactive iodine from entering the thyroid gland. The most important aspect here is that the thyroid gland is very sensitive to radioactive iodine. It is a mineral iodine salt used to block the absorption of radioactive iodine and protect against radiation damage.
KI cannot reverse damage once the thyroid gland has been injured. It does not provide protection against other radioactive elements.
Other Names are as Follows;
Dipotassium Diiodide
Potassium Diiodide

Iodide Solution
How is Potassium Iodide Produced?
Potassium Iodide production is carried out by several methods. It is produced by the absorption of iodine in potassium hydroxide. The reaction for this process is as follows.
3I2 + 6KOH 》5KI + KIO3 + 3H2O
The Potassium Iodate formed after the reaction is separated from the solution by filtration after the crystallization process. Even after this process, Potassium Iodate remains in the solution.
To produce Potassium Iodate from the remaining iodine in the solution, the solution is crystallized. Then, it is carried out at a temperature of 60 °C through carbon reduction to iodide or thermal decomposition method and a series of other processes.
2KIO3 》2KI + 3O2
What are the Physical and Chemical Properties?
It is an odorless white solid chemical.
Physically, it can be in Crystal, granular, or powder form.
Its boiling point is high. It is approximately 1323 °C.
Its melting point is 681 °C.
In terms of solubility, it has high solubility in water. For example, it is determined as 148 g/100 ml of water in water at 25 °C. It has low solubility in Ammonia and Glycerin.
Its density is 3.12 g/cm³. Therefore, it is more than 3 times denser than water.
It is sensitive to air. When exposed to moist air, it releases iodine and iodate. It exhibits hygroscopic properties in humid environments.
What are the Usage Areas of Potassium Iodide?
In areas where there is a risk of exposure to radioactive iodine, it prevents radioactive iodine from entering the thyroid gland immediately before or during exposure, and prevents hypothyroidism and acute thyroid disorders by blocking radioactive iodine from entering the thyroid gland.
Used as an Iodine source in the manufacture of cleaning agents with antimicrobial effects. Potassium Iodate can also be used.
Used in the poultry industry as a source of potassium needed by animals in the feed.
Used as a catalyst in elephant toothpaste experiments. It allows for the formation of dense and very high amounts of foam.
Used in the production of antiseptic hydrogels produced to ensure the healing of wounds and tissues. Sorbitol or Mono Propylene Glycol is used as a solvent in this application. Also, a cationic polymer will be required. Chitosan is used for this.
Used as Amine Salt Solvents to prevent the oxidative degradation of Monoethanolamine.
Used in the photography industry for the precipitation of silver.
Used in the medical field to regulate the thyroid gland.
Used to provide high foam formation in some reactions. It acts as a catalyst in this application.
Used as an analytical reagent in the laboratory. It is used in the determination of dissolved oxygen, dissolved chlorine, sulfur, and other analytes in water.
In the manufacture of ozone filter materials, Activated carbon, Citric acid, and Potassium Iodide are used together for impregnation.
Potassium Iodide and Calcium Iodide are used as a homogeneous mixture in table salts as an iodine supplement.
In recent years, although SDF is effective in arresting caries progression in pediatric dentistry applications, black staining issues occur. To prevent this, Potassium Iodide has the potential to prevent staining by reacting with silver ions.
What are the Factors Affecting Prices?
The price of Potassium Iodide is directly dependent on the prices of the chemical compounds used in its production. As the prices of Potassium Hydroxide and Iodine increase, the price of this chemical compound will increase.
Potassium Iodide prices have increased significantly in recent years. This is due to shipping problems caused by the covid-19 virus and the increase in freight rates.
Companies that are distributors of Potassium Iodide update their prices depending on their stocks.
