Product Overview
Gallium granules are made from high-purity Ga (gallium) with a purity of 99.99%. At room temperature, they are silver-white solids, which melt to a silver-white liquid at 29.76°C. Liquid gallium has excellent undercooling properties, remaining liquid even when cooled to 0°C, and is insoluble in water. Gallium expands by approximately 3.2% when heated, and its hardness ranges from 1.5 to 2.5. Gallium can wet glass surfaces, so it should not be stored in glass containers.
Features
- High Purity: Gallium granules are 99.99% pure, ensuring minimal impurity content, suitable for precision manufacturing and high-tech industries.
- Undercooling Liquid: Liquid gallium can stay in liquid form even at temperatures as low as 0°C, exhibiting excellent undercooling properties.
- Strong Wettability: Gallium can wet glass, which makes it unsuitable for storage in glass containers.
- High-Temperature Stability: Gallium remains stable at high temperatures, with low vapor pressure at around 1500°C.
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: Gallium granules serve as a catalyst in organic reactions, especially in esterification processes.
- Electronics and Optoelectronics: Widely used in the manufacturing of electronics, optoelectronics, LEDs, high-efficiency solar cells, display screens, and other high-tech fields.
