Abstract

The present work is concerned with the studies on the production of PZT ceramics by newly developed mixing process, which tentatively named "precipitation mixing method", consists of precipitating lead carbontate in the presence of $TiO_2$ and/or $ZrO_2$. Mixtures of $PbCO_3$ and $TiO_2$ or $ZrO_2$ were compared with those obtained by ball-milling with special emphasis on the rate and mechanism of formation of lead titanate and lead zirconate. A possiblity for obtaining PZT ceramics by "precipitation mixing method" was established.

본 실험에서는 혼합물중에서 한쪽 성분은 분체인 상태로 용액중에 분산시키고 이 용액중에서 다른 한 성분을 침전으로 석출시켜서 혼합물을 만드는 "부분침전법"이라는 새로운 혼합법으로 PZT ceramics를 만들기 위한 기초적 연구를 했다. 먼저 간단화 하기 위해서 $PbTiO_3$$PbZrO_3$의 생성반응을 개별적으로 검토했다. 그리고 이들 혼합상태가 ceramics 제조에 있어서 얼마나 중요한 인자인가도 다시 한번 확인시켰다.
