摘要：

The solubility limit of Ca in 99.99% pure -Al2O3 (alumina) was measured using a wavelength dispersive spectrometer mounted on a scanning electron microscope. Al2O3 samples were equilibrated at a concentration which ensured saturation of the Al2O3 grains with Ca, and were quenched in water from 1600 degrees C. The results were compared with those from samples which were furnace cooled from 1600 degrees C. For the quenched samples, the Ca solubility limit was found to be 51 +/- 1ppm, which is significantly larger than the solubility limit for samples which were furnace cooled (26 +/- 1ppm).
