通过测定几种氧化铝粉末压坯在空气中的等温收缩率，研究了氧化铝的初始烧结动力学。这些压坯的收缩可以通过晶界空位扩散模型在1200° C至1600°C的温度范围内最好地描述。压坯的行为是一致的模型后，初始收缩已经发生。对于相同的试样，这种初始收缩的大小是恒定的，并且与烧结温度无关。
The initial sintering kinetics of alumina have been studied by measuring the isothermal shrinkage of compacts of several alumina powders in air. The shrinkage of these compacts can best be described by a grain‐boundary vacancy diffusion model for the temperature range 1200° to 1600°C. The behavior of the compacts is consistent with the model after an initial shrinkage has occurred. The magnitude of this initial shrinkage is constant for identical specimens and is independent of the sintering temperature.
