Technology for development of PZT powder at 10 kg / batch
Technology developed for preparation of PZT-5H grade powder with high piezo-electric charge constant (d33 >550 pC/N) at 10 kg/ batch. The powder was prepared at 10Kg/batch with consistent properties from batch to batch.
Technology for Fabrication of PZT multilayered stacks by tape casting technique
PZT multi-layered stacks fabrication method is standardised using tape casting technique with PZT layers of thickness 90-100µm. These ML stacks were characterized by high block force (~ 5200N) and displacements. The technique can be extended for ML stack fabrication of other ceramic materials such as alumina, zirconia etc.
