삼염화인듐

생산 방법According to Klemm, metallic In is oxidized in InCl3 in a stream of Cl2, which has been carefully dried with concentrated H2SO4 and P2O5. A thoroughly dried quartz apparatus whose components have been fused or connected by ground joints is used. Chlorination proceeds rather vigorously at first, with a pale glow, and it proceeds through the mono- and dichloride steps. These compounds are melts. The end product of the chlorination, InCl3, sublimes around 600°C as lustrous spangles which appear on the walls of the receiver. The Indium chloride (LnCl3) may be purified by subliming in a stream of N2 (or CO2) to which some Cl2 has been added. The sublimate can cool in a stream of inert, Cl2-free gas to remove excess chlorine.
