A perspective on new ceramics and ceramic composites

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1987
Abstract The present status, characteristic features and important aspects of new ceramics and ceramic composites in high-technology industries are reviewed. Current problems requiring urgent solution are described, and some possibilities for solving them by introducing new ideas and results of some trials are discussed.

Toughening in Graphene Ceramic Composites

ACS Nano, 2011
The majority of work in graphene nanocomposites has focused on polymer matrices. Here we report for the first time the use of graphene to enhance the toughness of bulk silicon nitride ceramics. Ceramics are ideally suited for high-temperature applications but suffer from poor toughness.

Ceramic composites for biomedical applications

Clinical Materials, 1993
Ceramics have been successfully used for more than twenty years for orthopaedic prostheses, as articulating bearing surfaces against ceramic or polymer components. In both cases, ceramics are characterized by low friction coefficient and low wear rate, compared to metallic materials (stainless steels, titanium and chromium-cobalt alloys).

Ceramic Materials and Ceramic Matrix Composites

1992
Silicon nitride is one of the best candidates among non-oxide ceramics and has a very attractive combination of properties. Such as high strength at room and elevated temperatures high impact strength high strength-to-weight ratio high specific modulus (E/ρ) good creep resistance excellent thermal shock resistance ...

Biomimetic synthesis of ceramics and ceramic composites

Materials Science and Engineering: A, 2005
The processing of biomorphous ceramics and ceramic composites represents an advanced concept for manufacturing of porous or dense ceramic materials with microcellular morphologies. The cellular anatomy of naturally grown plants as well as there derived products such as cellulose fibre felts, cloth, papers and cardboard provide an attractive template ...

Microwave Sintering of Metal-Ceramic and Ceramic-Ceramic Composites

MRS Proceedings, 1994
ABSTRACTPolyphase ceramic and metal ceramic composites with at least one high dielectric loss component are potential candidates for application of microwave sintering, because of the high effectiveness of power dissipation and short sintering times.

Dynamic fracture of ceramics and ceramic composites

Materials Science and Engineering: A, 1991
Abstract The dynamic fracture responses of alumina (Al2O3), TiB2 particulate-SiC matrix and SiC whisker (SiCw)-Al2O3 matrix ceramic composites are presented in the context of dynamic fracture mechanics where a dynamic arrest stress intensity factor (SIF) did not exist in these brittle materials.

Ceramic nanoparticle technologies for ceramics and composites

2011
Nanoparticles provide interesting processing routes and material properties for many composites. For the fabrication of ZrO2 nanoparticles, a precipitation process followed by a hydrothermal treatment has been developed. For surface modification and deagglomeration to the primary particle size, a ball milling process and a kneading process have been ...

Glass Ceramics as Composite Fillers

Journal of Dental Research, 1974
Glass 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 2O3 are promising as X-ray opaque filler materials with nearly zero thermal expansion.

Tribology of Ceramics and Ceramic Matrix Composites

2013
Ceramic materials are well suited for tribological applications due to their superior hardness, high wear resistance, good chemical resistance, stability at high temperatures, etc. Ceramic pairs are commonly used in extreme environmental applications, such as high loads, high speeds, high temperatures and corrosive environments.
