摘要
对Ｐｂ＿（０．９９）Ｂｉ＿（０．０１）（Ｚｒ＿（０．９４）Ｔｉ＿（０．０６））Ｏ＿３和Ｐｂ＿（０．９９）Ｂｉ＿（０．０１）（Ｚｒ＿（０．６１）Ｔｉ＿（０．３９））Ｏ＿３两种主配方掺入Ｍｎ、Ｎｂ、Ｃｏ、Ｎｉ、ｗ等元素，制备出宽光谱吸收、电性能优良的掺杂ＰＺＴ热释电陶瓷。对其进行了结构分析和电性能测量，第一种配方的典型电学参数为：ε＿ｒ＝２１９；ｔｇδ＝０．００７８（２０℃，１ｋＨｚ）；ｐ＝４．４３×１０￣（－８）ｃ／ｃｍ￣２·Ｋ。
with conventional ceramic processing, the Pb_(0.99)Bi_(0.01)(Zr_(0.94)Ti_(0.06))O_3 and Pb_(0.99)Bi_(0.01)(Zr_(0.61)Ti_(0.39))O_3 pyroelectric ceramics doped with Mn,Nb,Co,Ni etc. are prepared. The microstruc- ture and electric properties of the ceramics are measured and discussed. The typical electric proper ties are:ε_r=219;tgδ=0. 0078(20℃,1kHz);p=4. 43×10￣(8)/cm￣2·K
