Composite pyroelectric ceramic material and preparation method thereof
The invention discloses a composite pyroelectric ceramic material and a preparation method thereof. The chemical general formula of the material is Pb {[(Me1/3Nb2/3)x(W1/3Fe2/3)1-x]y(Zr0.9Ti0.1) (1-y) }O3-nMe', wherein Me is Mg or Zn; x and y represent a mole fraction respectively, x is larger than or equal to 0.125 and smaller than or equal to 0.875, and y is larger than or equal to 0.08 and smaller than or equal to 0.11; Me' is a modified element and is one or more of Li, La and Sb, and the molar ratio range n is larger than or equal to 0 mol% and smaller than or equal to 5 mol%. The composite pyroelectric ceramic material has a higher pyroelectric coefficient and adjustable dielectric property, thereby having a better application prospect in various pyroelectric detectors.
