INVESTIGATION OF ULTRA HIGH TEMPERATURE PEROVSKITE TYPE CAPACITOR DIELECTRIC MATERIAL, by L. J. Timm. 5 May 61, 10p. illus. Lab. proj. no. 5940, pt. 4 Unclassified report DESCRIPTORS Ceramic capacitors, Ceramic materials, Dielectrics, Dielectric properties, Electrical properties, Physical properties, High temperature research, Temperature, Materials, Insulating materials, Electric insulation, Tests, Thermal insulation, Test methods, Life expectancy, Shock resistance. Values for AC loss characteristics of the perovskite type capacitor dielectric material over a wide frequency spectrum at temperatures up to 500 C were determined. Values for other electrical and some physical properties over the same temperature range were also determined. Results showed a large decrease in dielectric constant with increased temperature, poor and erratic thermal shock characteristics, and short life under voltage stress when aged at temperatures as low as 300 C.
