Germanium-Tetrachloride

Germanium(IV) oxide occurs in two forms one has a rutile lattice and melts at 1359 K whilst the other has a quartz lattice and a melting point of 1389 K. It can be prepared by oxidation of germanium using, for example, concentrated nitric acid, or by the hydrolysis of germanium tetrachloride ... [Pg.191]

Germanium tetrachloride refined for use in making optical fibers is usually specified to contain less than 0.5 to 5 ppb of each of eight impurities vanadium, chromium, manganese, iron, cobalt, nickel, copper, and zinc. Limits are sometimes specified for a few other elements. Also of concern are hydrogen-bearing impurities therefore, maximum limits of 5 to 10 ppm are usually placed on HCl, OH, CH2, and CH contents. [Pg.280]

GeCl4 Germanium is not a metal, so the standard binary guidelines apply germanium tetrachloride. [Pg.145]

Amongst the germanium compounds chosen, only germanium tetrachloride gave rise to an accident. Indeed, this compound undergoes extremely violent deflagration if it is poured into water. [Pg.210]
