Gallium Oxide Powder Properties
About Gallium (III) Oxide Ga2O3 Powder:
Gallium oxide is an organic compound that has the formula Ga2O3. This compound belongs to gallium oxide, a light blue solid with a 5.9g/cm3 density. Gallium oxide is stable at room temperature and has a high melting point, with a melting point of 2230°C.
Regarding the physical properties of gallium oxide, it has a crystal structure and can be processed by grinding or cutting. It has a high resistivity and can remain stable at high temperatures. In addition, gallium oxide has excellent thermal stability and can be used in high-temperature applications, such as sealing materials for high-temperature furnaces.
In terms of chemical properties, gallium oxide has strong oxidation. When it reacts with water, it forms hydroxide. If exposed to air, it will oxidize and become brown. In addition, intermetallic compounds are formed if gallium oxide is brought into contact with other metallic elements.

How is Gallium (III) Oxide Ga2O3 Powder Produced?

Gallium metal method: Dissolve gallium metal with a purity of 99.99% in a non-oxidizing solvent, such as anhydrous ethanol or acetone, and then add an appropriate amount of hydrogen peroxide for oxidation reaction to generate gallium oxide. After filtration, washing, and drying, high-purity gallium oxide can be obtained.

Gallium hydroxide method: Gallium hydroxide is dissolved in hydrogen peroxide solution and then heated through evaporation, cooling crystallization, filtration, and drying steps to obtain gallium hydroxide. Gallium oxide can be obtained by burning the gallium hydroxide at high temperature.

Gallium chloride method: Gallium chloride is reacted with hydrogen peroxide to produce gallium oxychloride, and then heated to a certain temperature for decomposition, gallium oxide can be obtained. This method is a simple and effective preparation method, but the cost is high and unsuitable for large-scale production.

High-temperature decomposition method: aluminum oxide and carbon are heated to high temperatures to produce elemental aluminum and carbon dioxide. The resulting aluminum is reacted with gallium chloride to form gallium chloride aluminum, which is then reacted with hydrogen peroxide to form gallium oxychloride. Gallium oxide can be obtained by heating the gallium oxychloride to a certain temperature for decomposition.

Electrolysis: A mixture of alumina and carbon is dissolved in a gallium chloride solution, and then electrolysis is performed to obtain gallium oxide on the cathode. This method can obtain high-purity gallium oxide, but the cost is high and unsuitable for large-scale production.

 Applications of Gallium (III) Oxide Ga2O3 Powder:

Analytical reagent: Gallium oxide can be used as an analytical reagent for detecting metal elements, such as gallium, indium, etc. It has the characteristics of high selectivity, high sensitivity, and rapid analysis and is widely used in trace element analysis in geology, environmental protection, chemical industry, and other fields.

Optical coatings: Gallium oxide has high light transmittance and high refractive index and can be used to prepare optical coatings. It is widely used in glasses, lenses, solar cells, and other fields and can improve light transmittance, reduce reflection, and increase wear resistance.

High-temperature material: Due to its high melting point and thermal stability, gallium oxide can be used as a high-temperature material. It can be used to prepare high-performance devices such as high-temperature transistors, integrated circuits, and lasers to improve the reliability and stability of these devices.

Electronic materials: Gallium oxide has high resistivity and low-temperature characteristics and can be used as an electronic material. It can be used to prepare electronic components, such as resistors, capacitors, etc., with high precision and stability advantages.

Catalytic material: Gallium oxide has high surface activity and catalytic performance and can be used as a catalytic material. It can be used as a catalyst carrier, automobile exhaust purification agent, etc., which can improve the activity and selectivity of the catalyst.
