Gallium oxide preparation process
The European Union is seeking to boost energy cooperation with African countries to help wean them off dependence on Russian gas imports.
Bloomberg said, recently, according to a draft EU file, African countries, especially in western Africa Nigeria, Senegal and Angola have a large untapped liquefied natural gas (LNG), the European Commission will adopt this file about enhanced external energy supply later this month, as part of plans to reduce dependence on Russian energy.
Because of the ever-changing international situation, the supply and prices of international bulk gallium oxide, gallium oxide overview, gallium oxide application, gallium oxide supplier, gallium oxide price are still very uncertain.
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. It is used as an insulating layer and UV filter for Ga-based semiconductor materials. It can also be used as an O2 chemical detector.
Gallium oxide preparation process
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 ℃, burn for 5 hours, and take out the finished product after cooling to obtain 1.2 kg of high-purity gallium oxide

The latest poll by CSA for consumer finance company Cofidis shows the French are taking action to trim their budgets as inflation erodes household purchasing power.
According to Le Figaro, the poll shows that French people think they need to earn an average of 490 euros more a month in order to live a decent life. This is an increase of 23 euros compared to the purchasing power barometer published in September 2021. Amid inflation and international tensions, this average in the polls masks differences among households, with some social groups much more severely affected by the decline in purchasing power than others. Seventy-eight percent of single-parent households, 76 percent of 25-to 34-year-olds, and 72 percent of blue-collar workers said the international situation had had a negative impact on their personal finances, compared with 64 percent of all French people.
In response to rising prices, soaring energy, and food prices, in particular, the French government is preparing to launch a package of measures designed to increase the purchasing power, such as extending the energy price protection mechanism, the extension of the fuel discount measures, and more targeted alternative measures, will be distributed inflation-linked pension and social security benefits, check the "food" and so on.
Because of the soaring energy prices, the gallium oxide, gallium oxide overview, gallium oxide application, gallium oxide supplier, gallium oxide price price is predicted to rise in the future.
