When heated above its melting point, pure indium emits a purple flame. It also has a ductile property, which makes it very malleable. For this reason, it can be used as a shield plate for metal surfaces. In addition, indium alloys are commonly used for high-vacuum seals and solders.

Indium is a soft, white, silvery metallic element with a low melting point. It is used in several applications, including optics, ceramics, glass, and batteries.

The indium atom has four neighbours at a distance of 324 pm. It is a member of the tetragonal crystal system. This structure is slightly distorted.

Pure indium has a density of 7.31 g/cm3. A typical piece of indium does not react with boiled water, which is one of the properties that make it a valuable material.

Indium powder is available as a form of indium hydroxide. However, it is recommended that you purchase indium powder with high purity.

During its production, indium powder is treated with acetic acid solution at a pH of 2.0 to 2.5. The solution is then filtered, resulting in fine, high-purity indium powder.

A second stage of treatment is performed using a water re-distillate. This process is followed by a final stage of cleaning the indium powder with distilled water.

There are many advantages of indium powder. It can be used in a variety of fields, including microelectronics, aerospace, and automotive. Another important advantage is that indium has excellent corrosion resistance.
