Self-lubricating ceramic tool materials synergistically toughened by nano-coated particles and silicon carbide whiskers

Assessment of exposure to quartz, cristobalite and silicon carbide fibres (whiskers) in a silicon carbide plant.

The main objective of the present paper is to report on the concentration of silicon carbide (SiC) fibres, crystalline silica and respirable dust in a Canadian SiC production plant and to compare the results with earlier investigations. The second objective is to tentatively explain the differences in concentration of the fibrogenic substances between different countries. The assessment of SiC ...

High Temperature Self-Lubricating Materials

Induction of mesothelioma after intrapleural inoculation of F344 rats with silicon carbide whiskers or continuous ceramic filaments.

OBJECTIVE To find whether continuous ceramic filaments (CCFs) and silicon carbide whiskers (SiCWs), which are used in many industries as reinforcing materials in advanced ceramic composites, are carcinogenic in the intrapleural inoculation assay. METHODS Samples of SiCWs, CCF, International Union Against Cancer crocidolite, or saline were injected into the pleural cavities of female F344/N ra...

Strengthening and stiffening carbon fiber epoxy composites by halloysite nanotubes, carbon nanotubes and silicon carbide whiskers

Ceria/silicon carbide core–shell materials prepared by miniemulsion technique

For the first time we present the synthesis of CeO(2)/Si(O)C core-shell particles prepared by the miniemulsion technique. The Si(O)C core was obtained by means of a polycarbosilane precursor (SMP10), which was subsequently functionalized with ceria and pyrolyzed to the ceramic. The size of these particles could easily be adjusted by varying the surfactants and the surfactant concentration, or b...
