Structure and Composition of Interfaces in Ceramics and Ceramic Composites

1998
The inherently brittle nature of ceramics, arising from their lack of plastic deformation mechanisms at ambient temperatures, subjects their macroscopic mechanical properties to microscopic flaws, such as processing voids, secondary phases, and/or grain boundaries.

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 ...

Gel technology in ceramics, glass-ceramics and ceramic-ceramic composites

Ceramics International, 1989
Abstract For many years, ceramists have been interested in sintering at low temperatures to manufacture devices that incorporate different materials sintering together, to deposit films on a substrate, to make fibers or ceramic-ceramic composites and to achieve fine-grained microstructures.

Fracture toughness of ceramics and ceramic composites

Ceramics International, 2003
Abstract The fracture toughness of zirconia, alumina, and silicon nitride ceramics, zirconia and alumina single crystals, silicon carbide as well as silicon nitride ceramic particulate composites, silicon nitride laminated composites, and other ceramics materials were studied by a single edge V-notched beam (SEVNB) method.

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 ...

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 ...

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.

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.

Cement, Ceramics, and Composites

2012
Cement and its applications as concrete (a composite of cement and aggregate) are known throughout the world. The most common cement used today is Portland, named after the gray rock of Portland, England, which it resembled. World production of Portland cement increased from 133 million tonnes in 1950 to about 1,000 million tonnes in 1985 and over ten ...

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.
