Solid- and liquid-state sintering kinetics in the (1[minus]x)ZnO-xBi[sub 2]O[sub 3] system with 0 [le] x [le] 0.05 over the range 600 [le] T(C) [le] 1,100 were investigated by impedance spectroscopy. Compositions with x < 0.002 retarded sintering, whereas compositions with x [ge] 0.004 accelerated sintering above the eutectic temperatures of 740 C. The results could be interpreted in terms of limited solid solubility of Bi[sub 2]O[sub 3] in ZnO (x [congruent] 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.
