CONTROLLED ATMOSPHERE FIRING FOR FORMATION OF BARRIER-LAYER DIELECTRICS.

Abstract

A new process was devised for producing barrier-layer dielectrics from high purity barium titanate. The process developed permits the formation of a dielectric with high capacitance per unit volume by a one-fire treatment with the use of controlled atmosphere in place of three separate firings presently required. A barrier-layer dielectric was produced that had a capacitance of 3400 picofarads in a bulk volume of 0.0062 cu in and dissipation factor of 0.035 at 1 kHz and room temperature. The capacitor demonstrated only a 20 percent decrease in capacitance with a 300-volt d.c. applied potential. (Author)
