| Abstract |
The conditions for the formation of β-silicon carbide whisker by vapor phase reaction in SiCl₄-Cl₂C = CH₂-H₂ system have been investigated. The conversion rate of SiCl₄ into SiC increased with reaction temperature and had been taken maximum value when the range of SiC1₄/Cl₂C = CH₂ mole ratio was from 2.5 to 2.8. The β-silicon carbide whisker can be formed in the range of reaction temperature from 1,100℃ to 1,500℃; SiCl₄/Cl₂C = CH₂ mole ratio, from 0.5 to 8.0,; total flow rate of the reactant gas at 300㎖/min. This whiskers were identified as the 8F type SiC by X-ray diffraction and had the length of 20㎛ or longer. |
