摘要：

Investigations were made on the penetration of CaO-Al//2O//3-SiO//2 glasses into dense polycrystalline aluminas. Initial penetration was along three-grain junctions or grain boundaries by a solution/reaction between the liquid and defect-containing alumina along interfaces. Degree of penetration was variable, and it was dependent on internal strain and MgO addition. Extended heat treatment reduced liquid penetration.
