Question

The ultraviolet radiant bulbs are made of quartz. Not of glass. Why?

Answer 1

Hint: We know that glass is made from ordinary sand and has common contaminants sodium oxide, magnesia, and alumina which absorbs ultraviolet lights. Quartz is nearly pure silicon dioxide which transmits ultraviolet lights. One of the chief contaminants in glass is water, but that is mostly an issue in the infrared spectrum.

Complete step by step answer:
The reason why ultraviolet radiant bulbs are made of quartz not of glass is because ultraviolet radiant is a form of electromagnetic radiation that comes from the sun. Sources like tanning beds and welding torches. Ultraviolet light has shorter wavelength than visible light, although ultraviolet waves are invisible to human eyes. If we use glass in place of quartz then glass will absorb ultraviolet rays while quartz does not. Ultraviolet radiant has a low power of penetration, hence it directly affects the human body as well.
Why do we use quartz?
The reason why we use quartz is because quartz will transfer ultraviolet rays from to since quartz is made of Silicon dioxide, glasses made up of abundant raw material like Sand and limestone.
So, in this way we can understand why quartz is used in making ultraviolet radiant bulbs.

Note: As we know silicon dioxide is used in quartz because, Silica commonly known in the form of quartz, is the dioxide form of silicon. Because it is usually used to manufacture glass, ceramics and abrasives. Quartz is the second most common mineral in Earth’s crust. That’s why silicon dioxide is used in ultraviolet bulbs. The main part we can remember is silicon.
