Abstract
This invention relates to multi-compositional, multiphase composite compositions comprising as phases thereof (i) an electronically conducting or semi-conducting substrate, (ii) an inorganic oxide composition layer in proximity to at least a portion of the surface of said electrically conducting or semi-conducting substrate and (iii) an inorganic crystalline molecular sieve composition layer upon at least a portion of the surface of said inorganic oxide composition layer. The inorganic crystalline molecular sieve composition layer is grown by crystal growth upon at least a portion of the inorganic oxide composition layer surface. The different phases of the composite compositions are substantially contiguous and exhibit a distinct compositional and/or structural heterogeneity of one phase to another. The multi-compositional, multiphase composite compositions have beneficial utility as a moisture sensing element in an electric hydrometer which measures the moisture content of moisture-containing systems by change in electrical impedance. This invention also relates to processes for preparing the multi-compositional, multiphase composite compositions.
