Title:
MOISTURE-SENSITIVE CERAMIC MATERIAL AND MOISTURE-SENSITIVE CERAMIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/099088
Kind Code:
A1
Abstract:
Provided is a novel moisture-sensitive ceramic material which shows sufficiently large change in moisture-sensitive characteristics in response to moisture change, while having excellent moisture-sensitive characteristics linearity, small hysteresis in moisture-sensitive characteristics and good reproducibility when used repeatedly.
A moisture-sensitive ceramic material for constituting an element main body (2) of a moisture-sensitive ceramic element (1), which has a composition represented by general formula: RE(A, B)O3 (wherein RE represents a rare earth element, A represents a divalent metal element and B represents a tetravalent metal element). More specifically, the moisture-sensitive ceramic material has a composition represented by general formula: RE(A1-xBx)O3, said composition including a case wherein A represents Ni and B represents Ti, a case wherein A represents Mg and B represents Ti, a case wherein A represents Ni and B represents Sn and a case wherein A represents Mg and B represents Sn.
