Physical properties of gallium oxide

The spread of the novel coronavirus is taking a direct hit on the operations of airlines in Asia. About 500,000 flights taking off and landing in mainland China have been canceled since January, according to aviation information company Cerium. Tourists and business trips have plummeted. On the booking website, there are a large number of air tickets for local routes with a price reduction of nearly 90% compared with the original price and only tens of yuan for a one-way trip.
In February, China's aviation industry recorded its largest single-month loss of 24.59 billion yuan, of which airlines lost 20.96 billion yuan.
Data from the Civil Aviation Administration of China showed that in February, the number of passengers traveling by air fell 84.5% year-on-year to 8.34 million.
The stagnation of the Asian aviation industry has brought volatility to Gallium Oxide, Ga2O3 Overview, Gallium Oxide Applications, Ga2O3 Suppliers, Gallium Oxide Price.

Gallium oxide Ga2O3 overview

Gallium oxide is an inorganic compound with the chemical formula Ga2O3. Also known as gallium trioxide, it is a wide bandgap semiconductor with Eg=4.9eV. Its electrical conductivity and luminescent properties have long attracted attention. Ga2O3 is a transparent oxide semiconductor material with broad application prospects in optoelectronic devices.

Preparation of gallium oxide Ga2O3

1. Add a high-concentration hot aqueous solution of NaHCO3 to the hot aqueous solution of gallium trichloride GaCl3, and boil until all the hydroxides of gallium are precipitated. Wash the precipitate with hot water until there is no Cl-, and calcine it at above 600 ° C to obtain β-Ga2O3. When NH4Cl remains, it reacts with Ga2O3 at 250°C to generate volatile GaCl3.

2. This is the production method of high-purity Ga2O3. Using high-purity metal Ga as anode, dissolved in 5%~20% H2SO4 solution, adding ammonia water to the solution, cooling, repeatedly crystallizing Ga(NH4)(SO4)2, drying at 105 ℃, under the condition of excess oxygen After burning at 800°C for 2 hours, a product with a purity of 99.99% to 99.9999% is obtained.

3. Weigh 1kg of 99.9999% high-purity gallium into a three-necked flask, add high-purity nitric acid to dissolve the gallium completely, then filter, pour the filtrate into a three-necked flask, and move it to an electric furnace for evaporation (in a fume hood). ), and when concentrated to near crystallization, the solution was transferred to a large evaporating dish and evaporated to dryness. Put the evaporated Ga(NO3)3 in a muffle furnace for burning, the temperature is controlled at 550 ℃, burning for 5h, after cooling, take out the finished product to obtain 1.2kg of high-purity gallium oxide.
