Production methods for metals and alloys for the electronics industry

In most cases, metals and alloys obtained through conventional smelting methods cannot meet the requirements of electronic device manufacturing. Even the most sophisticated electrolytic methods struggle to completely remove impurities that are harmful to electronic devices.

Therefore, when manufacturing internal components for electronic devices, high-purity metals and alloys produced using recently developed advanced smelting methods are often used. If metals and alloys obtained through conventional smelting methods are used, they must also undergo the most sophisticated modern purification processes to remove as many impurities as possible.

Currently, advanced smelting methods capable of producing high-purity metals with minimal impurities primarily include:

1. Powder Metallurgy

High-purity metals and alloys are obtained by compacting and sintering metal powders.

2. Metallothermic Reduction

Metals are produced through chemical reduction reactions in a vacuum, reducing medium, or inert gas.

In addition, methods such as vacuum melting and inert gas melting are not only suitable for producing high-purity metals, but are also suitable for further purification of metals obtained through conventional smelting methods.
