[50], Germanium is created by stellar nucleosynthesis, mostly by the s-process in asymptotic giant branch stars. [31] Like silicon, gallium, bismuth, antimony, and water, germanium is one of the few substances that expands as it solidifies (i.e. [21][22] The first major use was the point-contact Schottky diodes for radar pulse detection during the War. It is unstable, easily sublimated and oxidized at high temperature, and dissociates in moist air or inert atmosphere. [37], The first organogermanium compound was synthesized by Winkler in 1887; the reaction of germanium tetrachloride with diethylzinc yielded tetraethylgermane (Ge(C2H5)4). The dioxide is obtained as precipitate and converted with chlorine gas or hydrochloric acid to germanium tetrachloride, which has a low boiling point and can be isolated by distillation:[67]. In his report on The Periodic Law of the Chemical Elements in 1869, the Russian chemist Dmitri Mendeleev predicted the existence of several unknown chemical elements, including one that would fill a gap in the carbon family, located between silicon and tin. germanium disulfide lewis structure At least one metal selected from Group 10 is deposited on the medium pore zeolite and, optionally on the germanium aluminophosphate (AIPO) or a germanium silicoaluminophosphate (SAPO).
