Application
Gallium sesquioxide is reduced to gallium suboxide, Ga2O [12024-20-3] by common reducing agents. Also, heating the sesquioxide with gallium metal yields gallium suboxide. Heating with magnesium reduces the oxide to elemental form in a violent reaction:
Ga2O3 + 3Mg →2Ga + 3MgO
Heating with mineral acids yields corresponding gallium salts. When heated with a mixture of hydrogen and arsenic vapors at 600°C, gallium arsenide, GaAs is produced. When heated with alkali metal oxide at 1,000°C, alkali metal gallates, such as K2Ga2O6 are formed.

Protocol
Synthesis and Characterization of Cobalt Ferrate Hollow Spheres
Due to their low density and large specific surface area, micrometer or nanoscale hollow spheres generally have nanostructured walls and exhibit many physical and chemical properties that are different from solid particles, such as optical, electrical, and magnetic properties.
