Abstract

Solid- and liquid-state sintering kinetics in the (1 - x)ZnO-xBi2O3 system with 0 ≤ x ≤ 0.05 over the range 600 ≤ T (°C) ≤ 1100 were investigated by impedance spectroscopy. Compositions with x <0.002 retarded sintering, whereas compositions with x ≥ 0.004 accelerated sintering above the eutectic temperature of 740°C. The results could be interpreted in terms of limited solid solubility of Bi2O3 in ZnO (x ≅ 0.004 ± 0.002), solid-state sintering in the subsolidus, and liquid-state sintering above the solidus. A phase diagram for the ZnO-rich end of the system is proposed, based on these results.
