The bonding of glass ceramics to bone
International Orthopaedics, 1989In 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

Choice Reviews Online, 2002 Journal of Nuclear Materials, 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.

Bioactive glasses and glass-ceramics
Clinical Materials, 1993Bioactive 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.

Introduction to Biocompatible Glasses, Ceramics, and Glass-Ceramics
Glass ceramics and ceramics have a vast range of applications in tissue engineering and regenerative medicine. Biocompatible glasses and ceramics, including bioinert ceramics, bioactive glasses (BGs), and calcium phosphate have been reviewed in this chapter detailing the history, properties, structure, and application.Amirhossein Moghanian +3 more

Glass-ceramics for photonics: Advances and perspectives
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014Glass-ceramics are nanocomposite materials which offer specific characteristics of capital importance in photonics. This kind of two-phase materials is constituted by nanocrystals embedded in a glass matrix and the respective composition and volume fractions of crystalline and amorphous phase determine the properties of the glass-ceramic.

Glass Ceramics as Composite Fillers
Journal of Dental Research, 1974Glass ceramics are known that are transparent and colorless and have very low thermal expansions. Experiments are described to modify such glass ceramics by introduction of oxides of high atomic weight. Glass ceramics containing relatively large amounts of La 2 O 3

The dielectric properties of the strontium titanate aluminosilicate glass-ceramics described in the previous paper have been investigated over the frequency range of 10 to 1000 kHz and temperature range of −170 to 200° C. The dielectric properties were strongly dependent on the crystallization conditions, which determined the amounts of SrTiO3 and ...

Glass-ceramic materials may transmit visible light if either of the following conditions are operative: (i) the crystallites of all species are much smaller than the wavelength of visible light, or (ii) the optical anisotropy (birefringence) within the crystals and refractive index difference between crystals and glass are very small.
