Multielement composite pyroelectric ceramic material and preparation method thereof
The invention discloses a multielement composite pyroelectric ceramic material and a preparation method thereof. The chemical general formula of the material is xPb(Me1/3Nb2/3)O3-yPb(Fe1/2Nb1/2)O3-zPb(Zr0.9Ti0.1)O3-mMe', wherein Me is one of Mn or Zn; x, y and z are respectively a mole coefficient, x is greater than or equal to 0.01 and less than or equal to 0.07, y is greater than or equal to 0.01 and less than or equal to 0.07, z is greater than or equal to 0.9 and less than or equal to 0.92, and x + y + z = 1; and Me' is a modifying metal element, m is a mole coefficient, and m is greater than or equal to 0 mol % and less than or equal to 5 mol %. The multielement composite pyroelectric ceramic material provided by the invention has a high pyroelectric coefficient, proper dielectric properties and a low dielectric loss, and the electrical properties can be adjusted, therefore, the multielement composite pyroelectric ceramic material has a good prospect in devices such as pyroelectric detectors and the like.
