Abstract
The present disclosure relates to piezoelectric compositions of Formula I comprising Lead Zirconate—Lead Titanate solid solution. The disclosure further relates to a method of obtaining said composition, method of preparing/fabricating piezoelectric component(s) and piezoelectric component(s)/article(s) obtained thereof. The piezoelectric composition and articles of the present disclosure show excellent electromechanical characteristics along with very large insulation resistance (IR).
