High Purity Gallium (III) Oxide Ga2O3 Powder CAS 12024-21-4, 99.9%

Description of Gallium (III) Oxide Ga2O3 Powder  :

Gallium oxide is an inorganic compound with the formula Ga2O3. This compound belongs to one of the gallium oxides and exists as an oxide with a hexagonal crystal structure.

Gallium oxide appears as a light yellow or white powder at room temperature, with a density of 5.59g/cm³ and a melting point of 2573K, with high heat resistance, and easy to form an oxide film in air, and has a high degree of chemical stability to air and water.

Gallium oxide's electrical conductivity is between that of an insulator and a semiconductor, and it has a high resistivity. In the electronics and semiconductor industries, gallium oxide can be used as a semiconductor material with a semiconductor band gap of 3.4eV, slightly larger than the 3.1eV of silicon. Due to its unique band structure, it is used extensively in optoelectronic and electronic devices, such as high electron mobility transistors (HEMTs) and optoelectronic devices.

In addition, gallium oxide can also be used to manufacture high-efficiency photovoltaic materials. Its wide band gap and high photoelectric conversion efficiency make it one of the ideal materials for solar cells. Because of its capacity to endure high temperatures, it also has application potential in the field of aerospace.

In the biomedical field, gallium oxide can serve as a carrier of drugs for the delivery of drugs and also for drug-sustained release. Because of its excellent Biocompatibility as well as chemical stabilities， it is widely considered to be a material with good Biocompatibility.

Production Method of Gallium (III) Oxide Ga2O3 Powder：

Chemical Vapor Deposition (CVD) 

Chemical deposition by vapor is commonly employed to make the elements and compounds through which a thin layer is deposited on various substrates. This is a chemical reaction process involving gaseous reactants, usually carried out at high temperatures. In this process, the oxide of gallium can react with other gaseous reactants (such as oxygen) in the gaseous state and then deposit a thin film of gallium oxide on the substrate.

The specific steps are as follows:

(1) Place pure gallium or gallium alloy in a quartz boat and push it into a furnace for heating.

(2) The mixture of oxygen or air and nitrogen gas is passed into the furnace to react with the heated gallium.

(3) During the reaction process, gallium oxide will be deposited on the substrate in the furnace to form a GAN film.

The gallium oxide film obtained by this method has higher purity and crystal quality, but the manufacturing cost is higher, and the yield is lower.

High-temperature molten salt electrolysis method:

High-temperature molten salt electrolysis is a common method for the preparation of gallium oxide, which takes gallium metal as a raw material, dissolves it in molten salt (such as NaGa2), and then electrolyzes the molten salt in an electrolytic cell to produce gallium oxide.

The specific steps are as follows:

(1) Gallium is dissolved in molten salt (such as NaGa2) to prepare gallium molten salt.

(2) The gallium molten salt is pumped into the electrolytic cell, and oxygen is injected to carry out the oxidation reaction.

(3) After electrification in the electrolytic cell, gallium ions react with oxygen ions on the anode to form gallium oxide and adhere to the anode.

(4) Remove the anode from the electrolytic cell and separate the attached gallium oxide from the anode.

The purity of gallium oxide obtained by this method is higher, and the yield is larger. Still, a large number of high-temperature molten salts are needed as electrolytes, and special electrolytic equipment is required.

Application of Gallium (III) Oxide Ga2O3 Powder  :
