Question

What is made out of ultra - pure of germanium?

Answer 1

We need to know that germanium is a chemical element having the atomic number$32$ with symbol $'Ge'$. And this element is hard and brittle with lustrous properties. It contains grayish white metalloids present in the carbon group. And the germanium is almost chemically similar to elements like tin and silicon. The germanium is used in many applications and the economic value of germanium is very high.

Complete answer:
As we know that the semiconductor devices and transistors are made by using the ultra - pure germanium. The germanium occurs between the silicon and tin in the fourteenth group and fourth period. It has the properties of both metal and the non - metal. The germanium is a highly reactive element to occur as a free element in nature. And the structure of germanium is like a diamond with the chemical and physical properties similar to silicon.
Germanium is a semiconductor. Hence, it is widely used in the semiconductor industry. And these are used in electronic devices which are also used to prepare the alloys and used in fluorescent lamps.

Note:
We need to know that the ultra – pure germanium is used to prepare the semiconductor devices as well as the transistors. And the germanium is widely used in electronic devices and also used as a constituent of alloys and used in lamps. Because germanium is highly transparent to radiation. Thus, it is also used in the instrument for measuring and detecting such types of radiation.
