Question

Quartz is extensively used as a piezoelectric material, it contains:
a.) Pb
b.) Si
c.) Ti
d.) Sn

Answer 1

Hint: Piezoelectric materials are the materials which produce electric current when they are placed under mechanical stress. There are many materials which possess the piezoelectric property and quartz is one of them.

Complete step by step answer:
Quartz is a mineral which is composed of one part of silicon and two parts of oxygen atoms in a continuous framework of the silicon – oxygen tetrahedral $Si{{O}_{4}}$ compound. In this each oxygen is shared between two tetrahedra and given an overall formula of $Si{{O}_{2}}$. Quartz is the most abundant mineral which is found on the surface of earth. Quartz forms at all the temperatures and it is abundant in three types of rocks i.e. igneous, metamorphic and sedimentary rock. Quartz is a type of silicate and it is present in virtually every color.
The working of the quartz crystal is based on the principle of piezoelectric effect. Piezoelectric effect is an effect in which materials produce electric current when they are placed under mechanical stress. When mechanical stress is applied to a piezoelectric material it leads to change in the shifting of the positive and negative charge center of the material. This leads to the generation of external electric fields.
So, the correct answer is “Option B”.

Note: Quartz is one of the most useful materials found in nature. Its usefulness is due to its physical and chemical properties. It is very durable and chemically inert in contact with most substances. It is heat resistant and has electrical properties which make it very valuable in electronic products.
