Abstract
The ferroelectric and crystallization behavior of glass-ceramic compositions in the Pb5Ge3O11-PbTiO3-PbZrO3 system were investigated. Selected compositions were melted, quenched and milled into amorphous powders. Pressed samples crystallize completely into multiple ferroelectric phases at 600°C, and density to 95–98% of the theoretical density at 700–720°C. Oriented thick-films were prepared by screen printing, followed by melting and recrystallization. By varying the heat treatment conditions the size of the PG, PT, and PZT crystallites were controlled from submicron to < 10μm.
