Abstract

Crystallization of Mg0-AI20 3-Si02 glasses containing small amounts of Zr02 with or without Ti02 or Cu20 was studied. In addition to high mechanical strength and indentation hardness the crystallized glasses possessed ultra-high alkali resistance. X-ray diffraction studies revealed the presence of 8-quartz and tetragonal zirconia or Cu20 at the initial stages of crystallization, while cordierite, zircon, cristobalite etc appeared at elevated temperatures. DTA curves showed that crystallization was accelerated on addition of Ti02 or Cu20 while scanning electron micrographs also exhibited dense crystallization below 1000°C. Partial substitution of Ti02 by Zr02 improved the working characteristics of glasses melted for the production of conventional cordierite glass-ceramics; corrosion of refractories was also significantly reduced. © 1984 Taylor & Francis Group, LLC.
