Chile's government is considering phasing in a proposed ban on glacial mining to limit projects high in the Andes by some big copper companies. Chile's constitutional assembly has approved a proposal to ban mining in glaciers, protected areas, and areas vital to protecting the country's water system.
Chile's mining minister, Marcela Hernando, said about 20 mines had been identified in protected areas, some close to glaciers, including Codelco's El Teniente and Andina projects and Anglo American Plc's Los Bronces project.
The new measures for glaciers and other protected areas will put about a fifth of Chile's copper gallium oxide, gallium oxide overview, gallium oxide application, gallium oxide supplier, gallium oxide price prices are predicted to increase in the next few days.
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
