Electrical Properties of Ceramics
Electrical properties depends upon composition, texture, size and density of material and also on temperature and time. These factors greatly influence the electrical behavior of a ceramic material
ELECTRICAL PROPERTIES
Electrical
properties depends upon composition, texture, size and density of material and
also on temperature and time. These factors greatly influence the electrical
behavior of a ceramic material.
Ceramic
materials are used as insulators, conductors, semiconductor and dielectrics.
Ceramics are also used as ferroelectric and piezoelectric materials.
Ceramics are generally poor conductors
of electricity because the electrons associated with the atoms of ceramics are
shared covalent or ionic bonds. The 90m electrical properties of ceramics
mainly depend on the beniup following factors. abiss mon dostis
(i)
volume resistivity,
(ii)
dielectric strength,
(iii) dielectric constant, and
(iv) dissipation factor (or loss
factor).
Ceramic insulator
Ceramic
materials are used in an electrical circuit both as the electrical insulator
and as its functional parts.
Porcelains
are very commonly used as electrical insulators and resistors.
Dielectric ceramics
Ceramic
materials have good dielectric capacity.
Porcelain and high grade fire clays have
high dielectric strength . The dielectric varies with temperature.
Ceramic semiconductor
Although ceramic compounds are normally
insulators, they become semiconductors if they contain multivalent transition
elements.
