Question

8. List the uses of silicon and phosphorus. For 8 std.​

Answer 1

Answer:

Phosphorus is a vital plant nutrient and its main use – via phosphate compounds – is in the production of fertilizers. Just as there are biological carbon and nitrogen cycles, there is also a phosphorus cycle. Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and incendiary shells.

Silicon tetrachloride can be used as iridize glass. Hyperpure silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics and space-age industries.
