| Abstract |
| An attempt has been made to prepare ~-SiC fibres by the
reaction of SiO vapour with C fibres at a temperature> 1600°C
in an extended arc thermal plasma reactor. The C fibres
prepared by the thermal pyrolysis of cotton fibres are made to
react with SiO vapour generated during the plasma heating of
(Si02 + Si) charge at a temperature> 1600°C. X-ray diffraction
pattern confirms the formation of !}-SiC fibres. The SEM studies
reveal that the fibres thus synthesised have high aspect ratio
with an average diameter of 10-12 J!m and an average length of
250 J!Ill. |
