Gallium trichloride is colorless needle-like hygroscopicity crystal and a kind of organic gallium compounds, which fume when contact with moist in air and hydrolyze. It reacts violently in air. GaCl3 is covalent minor metal salt, which is bipolymer when its gas is at about 270℃. It tend to dissolve in water and emit a lot of heat. GaCl3 also tend to dissolve in ether, benzene and other organic solvents, when dissolve in liquid ammonia, it forms ammonia complex. When temperature is less than the heating point, gallium(III) chloride tend to sublime in vacuum. Gallium metal or gallium(III) oxide is the raw material.
GaCl3 is a highly reactive compound with unique chemical properties, making it an essential material in various industrial and technological applications. Its solubility in water and organic solvents, along with its role as a gallium source, enables its use in diverses fields, ranging from electronics to catalysis and material synthesis.
