Super low temperature sintering of semiconducting BaTiO/sub 3/ based PTCR ceramics
SENSORS, 2002 IEEE - Tập 2 - Trang 1223-1226 vol.2
Tóm tắt
Super low temperature sintering with liquid phase of semiconducting BaTiO/sub 3/ PTCR ceramics was discussed Samples were sintered at various temperatures from 800/spl sim/1300 /spl deg/C /spl times/ 0.5/spl sim/2hr with varied sintering aids. Experiment shows the La-doped BaTiO/sub 3/ with sintering aid BN can be sintered as low as temperature of 1000 /spl deg/C /spl times/ 0.5/spl sim/2hr. Sintering chemistry and physics, particularly in terms of the defect chemistry with sintering aid BN were described.
