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.

Cast Glass Ceramics

Dental Clinics of North America, 1985
The application of cast glass ceramics to restorative dentistry represents a major advancement in applied dental science. In addition to restoring an individual's teeth with a material that is both esthetically pleasing and anatomically correct, the physical properties are designed to guarantee optimal performance characteristics.

The bonding of glass ceramics to bone

International Orthopaedics, 1989
In this study the bonding behaviour of glass ceramics, containing apatite and wollastonite, to bone tissue is shown to vary depending on the amount of alumina they contain. We have experimented with three types of material: A.W-GC, AW-6 and AW-AL. Rectangular plates were implanted into the tibiae of rabbits. Ten weeks later a segment of bone around the

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‐

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 ...

Glass ceramics

Science of Ceramics, 1965
The literature on ceramic-like glassy cryst. products from glass is reviewed. The crystal phase of Pyroceram 9609 is cordierite (2MgO.2Al2O3.-5SiO2), with TiO2 as a seed-forming addn.: tan d = 3 * 10-4 at 100 Deg for a frequency of 24 * 1010 cycles.
