| Summary: | In this article, the Frenkel’s theory of liquid-phase sintering was
interpreted regarding pores as the activated volume. The mathematical model
established by Nikolić et al. was used to infer the equilibrium sintering
time at varied sintering temperatures during the isothermal sintering of
codierite glass by Giess et al. Through the calculation, the equilibrium time
at 800ºC, 820ºC, 840ºC and 860ºC is inferred to be 7014.42mins, 1569.65mins,
368.92mins and 114.61mins, respectively. The equilibrium time decreases as
the temperature increases. And the theoretical value is in good accordance
with the experimental results. Thus, the model established by Nikolić et al.
can be applied successfully to predict the equilibrium sintering time of the
cordierite glass at varied temperatures during isothermal sintering. |
