<p>PURPOSE:To obtain a cyrstalline sintered material useful as a detecting material for humidity sensor, having improved moisture responsive properties, by mixing blended powder of V2O3, TeO2 and Li2O with Ag2O to give raw material powder, melting the powder under heating, grinding the molten material to give glass powder, molding the glass powder and sintering it. CONSTITUTION:A base component mixture consisting of 52.5-57.5wt% V2O3, 40.0-45.0wt% TeO2 and 2.5-7.5wt% Li2O is further mixed with 8.0-12.0pts.wt. Ag2O to give starting raw material powder, which is melted under heating and made into glass. Then, the glass is ground to give glass powder, which is molded into a desired shape and sintered to give a moisture responsive sintered material of glass powder. The sintered material having improved susceptibility to moisture is obtained by common raw materials, given sintering can be carried out without requiring specific facilities and operation for crystal control and this process is advantageous with respect to cost. It is useful as a detecting material for humidity sensor used for various industrial devices, household electrical appliances, etc.</p> |
