锗是稀散元素,一直作为半导体材料使用。但随着硅材料的发展,锗在半导体上的应用逐渐被硅所代替。 早在四十年代就有人对锗的化合物(C和GeO_2)的生物化学特性进行了研究,并得出锗的毒性很低的一致结论。同时还有人根据燃煤(煤中含锗)工业区因空气中含一定数量的GeO_2,其结核病率低于一般环境工业区这一情况,实验了锗对结核
Ge is a rare earth element that has been used as a semiconductor material. However, with the development of silicon materials, the application of germanium in semiconductors has gradually been replaced by silicon. The biochemical properties of germanium compounds (C and GeO 2) have been studied as early as the 1940s and the unanimous conclusion that germanium has a very low toxicity has been drawn. At the same time, according to the coal-fired (coal containing germanium) industrial zone due to the air containing a certain amount of GeO_2, its tuberculosis rate is lower than that of the general environmental industrial zone, the experiment of germanium on tuberculosis
