The Relationship between A.C Impedance and Microstructure of a Sodium B-Alumina Cermic (MR-EC-003)

A comparison is made between the microstructures, resistivities and strengths of sodium B/B"-alumina samples prepared under different firing conditions. Double peak firing schedules are shown to result in samples of higher strength with a narrower grain-size distribution and lower resistivity than those produced by single peak firing. Complex plane a.c...
