Abstract:
     Semiconductive ceramic material for posistor which uses barium titanate as substrate is produced by proper sintering process. Various grain barium titanate and oxalic acid titanium barium oxide powder is mixed and used as main constituent. This process can produce high quality semiconductor thermal sensitive ceramic material, it has fine crystal grain, low ordinary temp. resistivity, large positive temp. coefficient of resistance, higher pressure intensity, large ratio of Rmax. / Rmin.
