PIEZO - ELECTRIC MATERIALS

The materials which exhibit piezo-electric effect are known as piezo-electric materials.

Quartz, rochelle salt, tourmaline and zinc blende are the best examples for piezo electric materials.

There are two main groups of piezoelectric crystals.

(i) Natural crystals such as quartz; tourmaline, etc.

(ii) Synthetic crystals, such as Rochelle salt, lithium sulphate, etc.
