Abstract

Ceramic resistors to be stable at high temperature were manufactured from using MgO, SiO2, SnO2, Bi2O3, and CeO2 by sintering in air at 125$0^{\circ}C$. Electrical resistivity with elevated temperatures was studied for the various system of the above oxides. The resistor, 1.0 MgO-1.0 SiO2-0.575 SnO2-0.005 Sb2O3-0.025 Bi2O3-0.013 CeO2 has the resistivity, (14.55$\pm$0.3)$\times$103 ohm in a temperature range from $25^{\circ}C$. to 80$0^{\circ}C$. It is concluded that the ceramics prepared by a dielectric compound and metal oxide semi-conductor has a good thermostability for electrical appliciations.
