Abstract

<abstract abstract-type="main" id="jace12442-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The solubility limit of Ca in 99.99% pure α‐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°C. The results were compared with those from samples which were furnace cooled from 1600°C. For the quenched samples, the Ca solubility limit was found to be 51 ± 1 ppm, which is significantly larger than the solubility limit for samples which were furnace cooled (26 ± 1 ppm).</p> </abstract>
