Abstract
In order to obtain knowledge to manufacture RuO2 thick-film resistors having resistance and the TCR controlled closely to the required value, RuO2 thick-film resistors were prepared with different variables, including various conductive particle sizes. glass particle sizes, thermal expansion coefficients of the glass, mixing ratios of the conductive element and glass, and additives, et al. Then the relation between these factors and electrical properties of the thick-film resistors was studied in experiments. As a result. it was found that when a special glass is chosen, its R-TCR curve is unconditionally fixed regardless of various preparation factors, and the R-TCR curve can be moved only by changing the thermal expansion coefficient of the glass. Then, oxides of various elements were added to RuO2 thick-film resistors and the electrical properties of the resultant resistors were examined. It was clarified that almost all the oxides of transition metals, rare earths, and antimony used as additives can closely control the resistivity and TCR of the resistors to obtain a required value. In addition, it was clarified that the principle of superposition applies to the additives. 10 refs., 13 figs., 3 tabs.
