Indium block refers to a high-purity indium metal material that exhibits a silver white appearance. Indium has a low melting point of approximately 157 degrees Celsius (313 degrees Fahrenheit). The density of indium blocks is about 7.3 grams per cubic centimeter, which has good ductility and malleability. Indium blocks have good conductivity and are a high-quality conductive metal. It has a relatively low resistivity at room temperature, about 82 micro ohm · cm, and can be used for applications such as manufacturing electronic components, circuit boards, and wires.

The production process of indium blocks mainly includes the following steps:

1. Indium ore extraction: Indium ore mainly exists in zinc ore and lead ore, and is generally mixed with other metal impurities. Firstly, the ore containing indium is extracted through processes such as mining and beneficiation.

2. Refining process: The extracted ore is refined to remove impurities and obtain high-purity indium raw material. This process includes steps such as smelting, electrolysis, and distillation, and different purity requirements can be achieved through different methods.

3. Casting and molding: Melt high-purity indium raw materials, then pour them into pre prepared molds, and form indium blocks through cooling and solidification. According to needs, different casting processes can be used, such as conventional casting, isostatic pressing casting, or single crystal casting, to obtain indium blocks of different shapes and sizes.

4. Surface treatment: The indium block produced may contain oxide films or other surface pollutants. In order to improve its surface quality, steps such as acid washing, polishing, or chemical treatment can be carried out to remove poor surface layers and improve the purity and smoothness of indium blocks.

5. Testing and Packaging: The indium blocks produced need to undergo strict quality testing, including chemical composition analysis, physical performance testing, etc. After passing the inspection, package and label the indium block for transportation and storage.
