Effect of Sintering Duration on Pure PZT for Piezofan Application

Abstract:

Recently, pure PZT have been used as a piezofan in electronic application. Properties that piezoelectric fan should have are high mechanical piezoelectric coupling factor, high dielectric constant, easily polarized and high piezoelectric charge constant. Soft PZT is a suitable candidate to fulfill this requirement. The samples will be prepared via high planetary mill; due to this process can skip calcinations process, which can reduce a lot of cost. This process also can avoid PbO loss during sintering process. The microstructure and electrical properties of PZT ceramic were found to be more sensitive to the sintering condition. Preliminary works have been done in order to find a suitable sintering duration in order to produce a good PZT formation. SEM analysis indicated that shorter sintering time promotes fine structure and densification. This have been proves where relative density of the obtained sintered PZT ceramics was measured to be approximately 99 % of the theoretical density.
