Abstract
This invention is directed to the production of thermally crystallizable glasses which can be crystallized in situ via heat treatment into glass-ceramic articles containing a nickel spinelloid as the predominant crystal phase. The glasses consist essentially, in weight percent, of 40-60% SiO.sub.2, 10-35% Al.sub.2 O.sub.3, 5-35% NiO, 0-20% MgO, and 0-15% total TiO.sub.2 and/or ZrO.sub.2. The preferred glasses contain at least 2% MgO.
