Gelcasting of PZT

摘要: Abstract Aqueous gelcasting of PZT is discussed in this paper. Concentrated suspension (50 vol.%) with low viscosity developed by using triammonium citrate as the dispersant. Zeta potential results suggest that effect TAC decreasing may be ascribed to its electrostatic stabilization mechanism. A premix solution containing 20 wt.% AM monomer can provide a mechanical strength 18 MPa for green body obtained from 50 vol.% suspension. SEM photos indicate ceramics homogeneous microstructure fabricated. Comparison piezoelectric coefficients gelcast samples those die pressed indicates additives, including monomer, crosslinker and dispersant etc., show no influence on property samples.
