The objectives of this work were to investigate the toxicity of silicon carbide whiskers and powders and silicon nitride whiskers and powders and to compare their toxicity with the toxicity of crocidolite. The effects studied were inhibition of the cloning effΔ±ciency of V79 cells, formation of DNA s

A two-step reaction scheme has been employed for the synthesis of SiC whiskers at 1450 ~ under an argon or hydrogen flow. First, SiO vapour was generated via the carbothermal reduction of silica in a controlled manner. Second, the generated SiO vapour was reacted with carbon-carrying vapours such as
We report on a method to produce Sic whiskers without the presence of metal catalysts by reacting carbon nanoclusters with SiO at 1700Β°C. The dark carbon nanotubes with hollow cores are converted to solid greenish Sic whiskers. Electron diffraction and EDX con&m that the product is Sic with a single
