PREPARATION OF LEAD ZIRCONATE TITANATE THROUGH A SPARK PLASMA SINTERING TECHNIQUE

摘要

Sintered body of lead zirconate titanate (PZT) was prepared through the spark plasma sintering (SPS) technique. When the mixture of raw materials was calcined at 800℃ and sintered at 900℃ for 10 min. with SPS technique, the sintered body had almost theoretical density but was a mixture of lead titanate (PT) and PZT. When a calcining temperature of 1100℃ was employed, sintered body had a single PZT phase but a lower density. High dielectric constant was obtained for a sample calcined at 800℃, sintered with SPS technique and fired again in the air at 1100℃.
