BATCH SINTERABLE AT LOW TEMPERATURES FOR MANUFACTURE OF PIEZOELECTRIC, CERAMIC FORMED BODIES AND FORMED BODY MANUFACTURED THEREFROM BY SINTERING

摘要

The invention relates to a low temperature sinterable batch (composition) based on lead zirconate titanate (lead titanate zirconate) for manufacturing formed piezoelectric, ceramic bodies. The batch contains a modifier that is a complex lead-free perovskite compound having the general formula: A<2+) B<5+>)O3, in which the symbols have the following meanings: A<2+> represents the elements calcium or strontium, B<3+> represents the element bismuth and B<5+> represents the elements antimony, niobium or tantalum. The invention also relates to a process for sintering the batch and to formed (shaped) piezoelectric manufactured by sintering.
