A lot of artificial ceramics as barium titanate, lead titanate
, lead zirconate-titanate (PZT), potassium niobate, lithium niobate, and lithium tantalite have similar properties.
A small sample of individual paper topics are sintering and dialectric properties of Nano-BaTiO3 powder synthesized by high-gravity reactive precipitation, effect of lead excess on the formation and dialectric properties of silver dispersed lead titanate
film, study of graphite/bakelite/BaTiO3-based PTC ceramics composite, and fabricating metal patterned ceramic substance by tape casting.
Typically ferroelectric ceramics, such as lead zirconate titanate, (PZT), lead titanate (PT) and barium titanate have been used as the transducer material in such sensors.
The ceramic used here was calcium modified lead titanate (PTCa) with the following composition
