Abstract (en)
[origin: WO03083428A1] The present invention discloses a relaxor material lead iron tungstate which has been synthesized in doped and undoped conditions by single and two step heat treatment. The relaxor material is seen to exhibit almost negligible hysteresis and a transducer made thereby shows pressure measurement capability over a wide range from 0.5MPa to 415MPa with accuracy of +/- 0.05%.
