Lead iron tungstate capacitive transducer, relaxor material therefor and method of manufacture of said relaxor material

摘要：

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 0.5 MPa to 415 MPa with accuracy of ±0.05%.

摘要（中）：

本发明公开了一种通过单次和两步热处理在掺杂和未掺杂条件下合成的弛豫材料钨酸铅铁。看到弛豫材料表现出几乎可忽略的滞后现象，由此制成的换能器在0.5MPa至415MPa的宽范围内显示出±0.05％的压力测量能力。
