Abstract:

The development of precision high temperature metal oxide film resistors suitable for operation at temperatures between -65 C and 500 C in nuclear environments for 1000 hours is discussed. Work on metal oxide film resistors indicated that stable resistive films could be obtained by depositing a tin oxide-antimony oxide film on high alumina substrates. This tin-antimony film was modified by the addition of organic or metallic additives to determine the effect of such additives. Other high alumina substrate materials were investigated, together with methods of cleaning the substrate materials prior to film deposition, to determine the best material for the preparation of stable resistors. An improved method of applying the flame-sprayed alumina protective coating was developed to minimize variations in the resistance resulting from the application of the coating. Extended load-life tests were made to evaluate the effects of changes in resistor preparation and also to evaluate the resistors as finally developed. Author
