Q. Which of the following is ferroelectric compound?
A) $BaTiO_{3}$
B) $Pb_{2}O_{3}$
C) $PbZrO_{3}$
D) $K_{4}\left\lbrack Fe(CN)_{6} \right\rbrack$
Explanation
(a)
The dipoles in certain solids are spontaneously aligned in a particular direction, even in the absence of electric field. Such substances are called ferroelectric substances. Barium titanate$\ (BaTiO_{3})$ and potassium hydrogen phosphate $(KH_{2}PO_{4})$ are ferroelectric solids
