Germanium ( IV) chloride is a chemical compound selected from the group consisting of germanium compounds and chlorides.

Production and representation

Germanium (IV ) chloride can be extracted with chlorine or hydrogen chloride by the reaction of germanium or germanium (IV ) -oxid/Germanium (II ) oxide.

Properties

Germanium (IV ) chloride is a colorless, fuming liquid with a pungent smell in the air ( by hydrochloric acid). It has a boiling point of 83 ° C and hydrolyzed with water or acids slowly germanium (IV ) oxide. With chlorides it forms chloro complexes of the type - GeCl62.

Use

Germanium ( IV) chloride is an important intermediate in the recovery of germanium, and the microwave preparation of Hexachlordigerman Ge2Cl6. High purity germanium (IV ) chloride is used in the production of optical fibers made ​​of quartz glass to form the core of the silica fibers, a high purity germanium ( IV) oxide layer.
