چکیده انگلیسی
Development of a low cost high pressure sensor with reasonable accuracy is always a challenge for researchers and metrologists. During last few decades, these relaxors have extensively been studied and found useful in several applications in capacitors, memories, optical wave guide, detectors, etc. The ferroelectric relaxor exhibits high strain response and high dielectric constant near the transition temperature. These properties attract researcher to use this material as pressure sensor. The present paper describes an effort made to find new application of ferroelectric material as pressure sensor. The present study carried out on pressure and temperature dependent dielectric properties of (1 â x) PbFe2/3W1/3O3-xPbTiO3 binary relaxor systems with x = 0, 0.02, 0.10 and 0.18 in the pressure range from atmospheric pressure to 416 MPa and temperature range from 283 to 323 K. In the present investigation, researchers have optimized the concentration of lead titanate (PT) in lead iron tungstate-lead titanate (PFW-PT) binary system to obtain high pressure coefficient and low temperature coefficient which is a prime requirement for a binary system to be used as a high pressure sensing element. The specimens are prepared by conventional mixed oxide route. The results thus obtained clearly establish the feasibility of use of PFW as pressure sensing element having low temperature and high pressure coefficient in the pressure range 0-416 MPa and temperature range 283-323 K.
