Glass and Glass-Ceramics

2012
The classic definition of glass is based on the historical method of formation: This is a very unusual way of defining any material. The result is that glass is now defined in several different ways.

Bioactive glasses and glass-ceramics

Clinical Materials, 1993
Bioactive materials are designed to induce a specific biological activity; in most cases the desired biological activity is one that will give strong bonding to bone. A range of materials has been assessed as being capable of bonding to bone, but this paper is solely concerned with bioactive glasses and glass-ceramics.

Glass and glass-ceramic photonic systems

SPIE Proceedings, 2017
The development of optically confined structure is a major topic in both basic and applied physics not solely ICT oriented but also concerning lighting, laser, sensing, energy, environment, biological and medical sciences, and quantum optics. Glasses and glass-ceramics activated by rare earth ions are the bricks of such structures.

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.

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‐

Ceramic and glass-ceramic lasers

Annales de Chimie Science des Matériaux, 2003
Les materiaux ceramiques actives par des ions luminescents se revelent etre des substituts prometteurs des monocristaux comme source laser, grâce notamment a une synthese moins difficile et une capacite de dopage accrue. Bien que ces materiaux ceramiques soient synthetises depuis les annees 60, ce n'est que recemment qu'ils sont devenus vraiment ...

Properties of Glass-Ceramics, Photosensitive Glasses, and Photosensitive Glass-Ceramics

1970
Photosensitive glasses possess a number of valuable properties, such as high strength, good stability, grain-free image, accurate reproducibility, multiplicity of contrast shades possible, and constancy of size in two and three dimensions, i.e., three-dimensionality of the image, which may extend to a certain depth or through the entire thickness of ...
