Bismuth ruthenate and silver were selected as conductor phases and the mixture of calcium oxide - alumina - silicon dioxide ( cao - al _ 2o _ 3 - sio _ 2 ) glass and lead oxide - boron oxide - silicon dioxide ( pbo - b _ 2o _ 3 - sio _ 2 ) glass was selected as inorganic binder phases . it was found that , with the increasing of volume fraction of silver and conductor phase , sheet resistivities descend and there are critical thresholds 实验发现,随着功能相百分含量的增加,电阻膜层的方阻值逐渐减小,存在两个临界阈值,电阻温度系数偏向正值;功能相中银百分含量增加,膜层的方阻值逐渐减小,有一个临界阈值,电阻温度系数偏向正值。
