Description
Existing amount in the earth crust is 0.05ppm and it’s generated from zinc sulfide; separate from the ashes in the zinc metallurgy, obtain the liquid of indium ion (3 of +) and make it highly pure singular matter through electrolysis. It occurs as silver white crystal. It’s soft and belongs to square crystal system. It’s stable in the air and generate In2O3 after heated up. In room temperature it can react with fluorine and chloride. It can solve in acid but not in water or alkaline solution.
