Sintered feldspar glass–ceramics and glass–ceramic matrix composites

Ceramics International, 2008
Abstract Sintering with simultaneous crystallization of fine glass powders allowed the preparation of dense glass–ceramics based on unusual feldspar crystals (constituted by microcline and orthoclase, KAlSi 3 O 8 ), at a very low temperature (750 °C) and with limited processing times.

The cast glass-ceramic restoration

The Journal of Prosthetic Dentistry, 1987
The use of Dicor cast glass-ceramic material for fixed prosthodontic complete crowns has been described. The advantages of this material are chemical and physical uniformity, marginal accuracy, uncomplicated fabrication from wax-up to casting, ceramming, and coloring, ease of adjustment, excellent esthetics resulting from natural translucency, light ...

Glasses, ceramics, and glass‐ceramics containing carbon or nitrogen

Advanced Materials, 1993
Non‐oxide ceramics, for example SiC, Si3N4 and other carbides and nitrides, have been shown to have properties, particularly at elevated temperatures, which make them suitable for use under exacting environmental conditions. These materials are discussed along with partially carbon‐ and nitrogen‐substituted glasses and ceramics such as sialons (Si‐Al‐O‐
