About Gallium (III) Oxide Ga2O3 Powder:
Gallium oxide is an inorganic compound with the chemical formula Ga2O3. Gallium trioxide, also known as gallium trioxide, is a wide bandgap semiconductor, Eg=4.9eV.
What type of substance is gallium oxide? Gallium Oxide is a highly insoluble thermally stable Gallium source suitable for glass, optic and ceramic applications. The precipitation of the hydrated form of gallium oxide is caused by the neutralization of acidic or basic gallium salt solution. Oxide compounds are not conductive to electricity.
Is gallium oxide a gas? Gallium(I) oxide is a brown-black diamagnetic solid which is resistant to further oxidation in dry air. It starts decomposing upon heating at temperatures above 500 °C, and the decomposition rate depends on the atmosphere (vacuum, inert gas, air).
Its electrical conductivity and luminous properties have long attracted people's attention.Ga2O3 is a transparent oxide semiconductor material, which has broad application prospects in optoelectronic devices. It is used as an insulating layer of Ga-based semiconductor materials and ultraviolet filters. It can also be used as an O2 chemical detector.
Ga2O3 can react with fluorine gas to form GAF3, which is dissolved in 50% HF to obtain the product GAF3 ·3H2O.Ga2O3 can be dissolved in slightly hot dilute nitric acid, dilute hydrochloric acid and dilute sulfuric acid.Ga2O3 after burning is insoluble in these acids or even concentrated nitric acid, and insoluble in an aqueous solution of a strong base. It can only be dissolved by melting NaOH, KOH or KhSO4 together with K2S2O7. Gallium chloride is produced by melting with an excess of twice as much NH4Cl at 250℃. At red heat, Ga2O3 reacts with quartz to form vitreous, but no new compounds are formed on cooling. Red heat can also react with glazed porcelain crucible.
Is gallium oxide toxic? Oral LD50: 10000 mg/kg (mus), therefore low toxicity by ingestion. Rats exposed by inhalation to gallium oxide 2 hours/day for 20 days developed severe pulmonary inflammation (alveolitis) evolving to fibrosis.

Performance of Gallium Oxide Ga2O3 Powder :
Gallium oxide is a white triangular crystalline particle with the chemical formula Ga2O3, insoluble in water, and slightly soluble in hot acid or alkaline solutions. Ga2O3 is easily soluble in alkali metal hydroxides and dilute mineral acids.
Technical Parameter of Gallium Oxide Ga2O3 Powder :
How is Gallium (III) Oxide Ga2O3 Powder Produced?
1. Add a high concentration of NaHCO3 to the hot water solution of GaCl3 and boil until all the gallium hydroxide is precipitated. The precipitation is washed with hot water until there is no Cl-, and calcined above 600℃ to get β-Ga2O3. When NH4Cl remains, it reacts with Ga2O3 at 250℃ to form volatile GaCl3.
2. This is the method of making high-purity Ga2O3.Ga(NH4)(SO4)2 was crystallized repeatedly, dried at 105℃, and burned at 800℃ for 2h under the condition of excess oxygen. The product with a purity of 99.99% ~ 99.9999% was obtained.
3. Put 1kg99.9999% of high purity gallium into a three-necked flask, add high purity nitric acid, dissolve all gallium, then filter, pour the filtrate into a three-necked flask, and move to the electric furnace for evaporation (in the fume cupboard). When the concentration is close to crystallization, move the solution into a large evaporation pan and evaporate to dry. The evaporated Ga (NO3) 3 was burned in a muffle furnace at 550℃ for 5h. After cooling, the finished product was taken out and 1.2kg of high purity gallium oxide was obtained.
Applications of Gallium (III) Oxide Ga2O3 Powder:
Gallium oxide has been used in the study of lasers, phosphors and luminescent materials. Gallium oxide is also used as an insulating barrier for tight connections.
Monoclinal β-Ga2O3 is mainly used in gas sensors and luminescent phosphors, and can also be used in the dielectric coating of solar cells.
In semiconductor; Gas sensing; In the field of catalysis, gallium oxide has also been used.
Applications of gallium oxide nanostructures as blue and ultraviolet light emitters in optoelectronic devices.
This stable oxide also shows potential for deep ultraviolet transparent conductive oxides and transistor applications.
Ga2O3 thin film has important commercial value as a gas-sensitive material.
Ss-Gallium (III) oxide is used to produce Ga2O3-Al2O3 catalyst.
Storage Condition of Gallium Oxide Ga2O3 Powder :
The damp reunion will affect Ga2O3 powder dispersion performance and using effects, therefore, gallium oxide should be sealed in vacuum packing and stored in cool and dry room, the gallium oxide can not be exposure to air. In addition, the Ga2O3 powder should be avoided under stress.
Packing & Shipping of Gallium Oxide Ga2O3 Powder :
