Abstract
1476374 Thermistors NIPPON TOKUSHU TOGYO KK 21 June 1974 [21 June 1973] 27631/74 Heading H1K In an oxygen ion transport type thermistor comprising a solid solution consisting of 50- 95 mol. per cent of an oxide of a tetravalent metal of Group IVB, the lanthanide series or the actinide series and 50-5 mol. per cent of oxide(s) of divalent alkaline earth metals and/or trivalent metals of Group IIIB including the lanthanide rare earth metals and having two metal lead wires embedded therein, the solid solution has a porosity of 7-55%. The porosity, which is preferably 15-35% e.g. 25%, is sufficient to permit an adequate supply of oxygen to the body but not so large as to adversely affect the mechanical strength of the body and the adhesion of the embedded electrodes. The tetravalent metal oxide may be ZrO 2 , CeO 2 , HfO 2 or ThO 2 . The divalent metal oxide may be CaO, MgO or SrO, and the trivalent metal oxide may be La 2 O 3 , Y 2 O 3 , Yb 2 O 3 , Sc 2 O 3 , Gd 2 O 3 or Nd 2 O 3 . The electrodes may be platinum or platinum-rhodium alloy wires. In an example a mixture of powdery ZrO 2 and CaCO 3 has added to it 4% by wt. of an emulsion of equal weight amounts of stearic acid and water and is pulverized for 20 hours. A mould containing the spaced platinum electrode wires is filled with the resulting mixture, the moulded mixture then being pressed at 2,000 Kg/cm.<SP>2</SP> and fired at 1,400-1,800‹ C. in air to produce the thermistors. In another example a spinel of MgO and Al 2 O 3 is added to the mixture as a resistance controlling agent. Numerous examples with the results of tests thereon are given.
