It can be commonly believed that selected countries including the United states and China keep stock – countrywide stockpiles – of germanium, as a result of predicted new developments in technological applications and its recent importance in armed forces and aerospace infrared imaging gear.
It's exclusive Houses of transmission and Index of Refraction from the infrared spectrum which satisfies it for infrared optics. While our eyes are unable to see by way of Germanium, infrared radiation (Specifically 8-14 um) is quite transmissive via it.
New applications are establishing in telecommunications and electronics for germanium, pushing demand from customers up and providing rise to an important drive for germanium recycling.

Even so, This is when they start diverging. Silicon is much lighter which has a density of 2.33g/cm3, making it ideal for pounds-sensitive apps and lower than 50 percent the density of germanium. Furthermore, it is much more thermally resistant than germanium and that has a Knoop Hardness of 1150 Additionally it is more durable and less brittle. Silicon also fees considerably less rendering it an even better prospect in numerous applications.
