Product Overview
Gallium ingots are high-purity, silver-white metals with a melting point of 29.76°C and a boiling point of 2403°C. At room temperature, they are solid and silver-white, but upon heating to their melting point, they become liquid. Gallium has unique physical properties, such as the ability to undercool below 0°C without solidifying in its liquid state, and it has high solubility and wettability. Gallium is stable in dry air but can hydrolyze, especially under physiological pH conditions. Its volume increases by about 3.2% when transitioning from liquid to solid. Gallium's high purity makes it valuable in electronic and precision industries.
Features
- High Purity: Available in 4N to 6N purity, ensuring very low impurity content, ideal for precision manufacturing and high-tech applications.
- Low Melting Point & High Boiling Point: With a melting point of 29.76°C and a boiling point of 2403°C, gallium is suitable for a variety of high-temperature applications.
- Unique Liquid and Solid Properties: Gallium remains stable in its liquid form and can undercool, with the ability to wet glass surfaces at high temperatures.
- Volume Expansion: Gallium expands by approximately 3.2% when transitioning from liquid to solid.
Applications
- Semiconductor Manufacturing: Used in the production of gallium nitride (GaN), gallium arsenide (GaAs), gallium phosphide (GaP), and germanium semiconductor dopants.
- Nuclear Industry: Pure gallium and low-melting alloys are used as heat exchange mediums in nuclear reactions.
- High-Temperature Measurement: Gallium is used as a filling material in high-temperature thermometers.
- Organic Reaction Catalysis: Used as a catalyst in organic reactions, particularly in esterification processes.
- Electronics and Optoelectronics: Widely used in the manufacturing of electronic devices, optoelectronics, LEDs, and other high-tech applications.
