Iodine is found in abundance on the earth. There are plenty of applications of iodine that makes it a popular element. It is a pure element which is lustrous purple-black non-metal solid that is found under standard condition. Iodine changes into solid to the gaseous state and releases a purple vapour. Though it is a non-metallic substance, it has some metallic characteristics as well.

Iodine is an essential element that we need in our everyday life. From household to industries, iodine is used everywhere. The wide range of applications makes iodine a popular non-metallic element. It is essential to understand the properties of iodine before putting into use.

Facts About Iodine

Iodine is widely used in household and industries. Due to chemical properties, it has emerged as a prominent non-metallic substance that has a wide application area. Here are a few facts regarding iodine that makes it quite accessible in the industries.

• Least Reactive: When it comes to reactivity, iodine is the least reactive member in the family of halogens that
also comprises of chlorine, fluoride and bromine.
• Appearance: Iodine looks grey to purplish-black, and when it is heated its vapour appear purplish.
• Melting/Boiling Point: Iodine starts melting at 113 degrees Celsius and boils at 185 degrees Celsius.
• Compounding Nature: Iodine is a friendly element that can compound with all the elements except inert gases,
sulfur, and selenium.
• Density: Iodine is not a dense element, it has a density of 4.93 grams per cubic centimetre
• Room Temperature State: At room temperature iodine will be found in a solid-state.
• Isotopes: The number of isotopes in iodine is 37.
• Atomic Number: 53

Applications of Iodine

Iodine is a non-metallic substantial element that is used for many industrial and household uses. If you are looking for crude iodine suppliers, there are plenty of credible names in the market. It depends on you as a buyer to make a well-informed decision before making a purchase. Before searching for the right supplier, it is essential to understand the different applications of the iodine.


The medical and pharmaceutical industry is the most benefited sector that has been utilizing iodine.

Hence, it is essential to find a reliable supplier for iodine that can best suit the purpose of medicinal use.


Another widespread use of iodine is in the photography industry. The reason why we can see the pictures clicked from a camera is because of iodine. The silver sheet that reflects the image on the film is made of iodine that helps in making the image clearer and detailed. It is generally called the silver iodine that is one used in photography films. The surface of the sheet is covered with silver iodide grains, and when the light is reflected on the sheet, the manifest image is formed.

Weather Modification

Even meteorologists have been using silver iodide. They generally use it for cloud seeding, which is basically a weather modifying method. The crystals of iodine serve as the nuclei around which water starts condensing and increase the chances of precipitation. Silver iodide is being used by the weather department for quite a long time.

Optical Polarizing Film

It is quite evident that polarizers are used in different optical instruments. As mentioned earlier, iodine is also used in preparing dyes, iodine-based films make quality polarizer. Ideally, they are used in LCD displays (liquid crystal enhancer).

Radioactive Tracer

Another critical application of iodine is acting as a radioactive tracer. It is a radioactive isotope that releases radiation when it passes through a medium. A receiver (iodine) tracks the progress of the isotope. It is majorly used in medical diagnoses, such as ultrasound, X-ray, nuclear imaging, CT sans, etc. The medial sector is benefitted mainly by the supply of iodine. Other than the medical industry, radioactive tracers are also installed in oil refineries to detect the faults and leaks in the machinery.

The Bottom Line

Iodine is a popular non-metallic substance that is widely used in industrial and household purposes. It is essential to understand that the unique properties and characteristics of iodine make it popular among the industry. From medical equipment to photography tools, iodine is used in plenty of areas. It is crucial to find the best iodine suppliers who can adhere to your requirements and provide you with quality iodine.

The above mentioned were some of the vital information applications of iodine that you need to know before making a purchase decision. From medical to the photography industry, iodine has been proven beneficial in our everyday lives. Furthermore, it is essential to make a well-informed decision regarding the iodine supplier.
