Development of High Drive,Stable Piezoelectric Ceramic.

摘要

Lead zirconate titanate compositions with zirconia to titania ratios of 51/49to 57/43were studied. Lead substitutions with barium,cadmium and strontium were made plus doping with LaFeO3, NaSbO3, MnO2, Fe2O3, U2O8and Cr2O3. Materials were prepared by hot pressing and atmosphere sintering and tested for aging,high field drive and axial stress sensitivity characteristics. Results of a pilot production run of standard ring specimens fabricated from the composition (Pb(.94) Sr(.06))(.980)(Zr(.51) Ti(.49))(.995) Cr(.015) Mn(.005)O3are presented. (Author)
