High Purity Gallium Metal Ga CAS 7440-55-3 For Semiconductor Material

Gallium (element symbol Ga) is a unique metal element that exists in liquid form at room temperature, with a melting point of only 29.76 ° C, which is the widest temperature range of liquid metals in nature. Gallium not only has magical physical properties, but also shows a wide range of application values in many fields.

In the field of electronics, gallium is an important part of semiconductor materials, which is used to manufacture high-frequency electronic tubes, microwave devices and photoelectric devices such as lasers, solar cells, etc., significantly improving the performance of electronic devices. In addition, gallium alloys are widely used in the aerospace, automotive and construction industries to manufacture key components due to their excellent mechanical properties and corrosion resistance.

Gallium also has good optical properties and is an important raw material for manufacturing optical materials and optical communication devices. In terms of lighting technology, gallium is a key material for LED chips, which has promoted the rapid development of semiconductor lighting technology and provided strong support for environmental protection and energy saving.

Description

Gallium is a gray blue or silver white metal. Its melting point is very low, but its boiling point is very high. Pure liquid gallium has a significant tendency of supercooling, which is easy to oxidize in air and form oxide film. Gallium is a by-product in the process of aluminum and zinc smelting, but the gallium obtained from sphalerite is very little. Most of the gallium is extracted from the crude aluminum hydroxide solution in Bayer process. Sodium gallinate is obtained by electrolysis of mercury battery and hydrolysis of amalgam in sodium hydroxide, and then gallium is obtained by electrolysis. Semiconductor gallium is purified by regional melting technology, or single crystal is extracted from the molten material (i.e. Chai's method).
