Electrical conduction in thick film resistors

The formation and electrical properties of the conductive network in RuO2 thick film resistors were investigated. As a result, a RuO2 thick film resistor having a high concentration of RuO2 has conductive chains of RuO2 and metal-like conduction. However, the resistor having a low RuO2 concentration has a reactive Layer that allows it to maintain its conductivity even though there are no conductive paths by mutual contact of RuO2 particles; it also has amorphous, semiconductor-like characteristics.
