Gallium oxide
It is an organic compound having the chemical name Ga2O3. Galium trioxide is another name for it. It’s a semiconductor of wide bandgap with Eg=4.9eV. With excellent electrical conductivity, light-emitting and other characteristics it can be used to detect O2 gas.
Gallium (III), or gallium trioxide is the most stable form of gallium oxides. The oxidization of metal gallium can be done by heating it in air, or by calcining galium nitrate and gallium hydroxide at 200-250degC.
Ga2O3 is capable of reacting with many metals under heating conditions. A crystal structure for gallate M(II-GaO2) was obtained from an alkali metaloxide reaction. It is above 400. Similar to Al2O3 or Ln2O3, this can be produced by reaction with CoO, ZnO.
2. This is the method for making high-purity gallium dioxide. Use high-purity Ga as an anode. Dissolve it in a 5-20% H2SO4 solution. Add ammonia to this solution and cool. Crystallize Ga(NH4)(SO4)2 several times before drying it at 105 degrees C. The product will be pure at 99.99%-99.9999% if it is burned for 2 hours at 800°C.
3. Add 1 kg of 99.9999% pure gallium to a 3-necked flask. Then, use high-purity, nitric acids to dissolve the gallium. After the solution has crystallized to a certain point, transfer it to an evaporating dish. For burning, place the Ga(NO3)3 that has evaporated in a muffle oven. Keep the temperature at 550 for five hours. Once the product has cooled, it is removed and 1.2kg high-purity gaium oxide is obtained.

The Property of Gallium Oxide
Gallium oxide are triangular, white, crystalline crystal particles. They are insoluble when mixed with water.Gallium (III), or gallium trioxide is the most stable form of gallium oxides.

Gallium Oxide Preparation
1. Combine a concentrated hot, aqueous NaHCO3 with the hot gallium chloride GaCl3 and heat until it is boiling. You can then wash the precipitate using hot water to remove any Cl-. To make volatile GaCl, NH4Cl will react at 250degC with Ga2O3 if it is still present.2. This is the method for making high-purity gallium dioxide. Use high-purity Ga as an anode.
