由于锆钛比为0.94/0.06时,锆钛酸铅固溶体处于低温铁电三角相与高温铁电三角相及反铁电正交相的三相交界区。实验证明采用0.94/0.06的锆钛比并加入适量软性添加物后使PZT固溶体的相变点接近室温,并使PZT固溶体在改变时引起的晶格畸变小,从而获得低介质损耗、低介电常数与高热释电系数的改性
As the zirconium-titanium ratio is 0.94 / 0.06, the lead zirconate titanate solid solution is in the three-phase junction of the low temperature ferroelectric triangular phase and the high temperature ferroelectric triangular phase and the antiferroelectric phase. Experiments show that using 0.94 / 0.06 zirconium-titanium ratio and adding appropriate amount of soft additives PZT solid solution phase transition point close to room temperature, and the PZT solid solution in the change caused by small lattice distortion, resulting in low dielectric loss, low dielectric Modification of electric constant and pyroelectric coefficient
