<p>46,760 A PRE-GLASSING METHOD OF PRODUCING HOMOGENEOUS SINTERED ZnO NON-LINEAR RESISTORS A method of making a homogeneous sintered body, which can exhibit non-linear V-I characteristics, comprises the steps of: (1) forming a single phase, chemically homogeneous glass, from a mixture of oxides containing at least Bi2O3, which is effective to cause non-linearity within a ZnO ceramic body, (2) mixing 2.5 wt.% to 40 wt.% of the single phase, chemically homogeneous Bi2O3 type glass, with 60 wt.% to 97.5 wt.% of ZnO particles, to form a uniform mixture, (3) pressing the glass-ZnO mixture, to form a consolidated body, and (4) sintering the pressed body, to form a ceramic body consisting of ZnO particles and a chemically homogeneous insulating layer formed from the Bi2O3 type glass coating the ZnO particles and bonding the ZnO particles together.</p> |
