Abstract

SubmicroStructure of Silicon Carbide Derived from Poly(methylchlorosilane).-Poly(methylchlorosilane) characterized by Si domains in the macromolecules is pyrolysed at 165 • C. SiC, Si, and C areas of nanoscale dimensions are detected by Raman spectroscopy at the resulting structure. The Si and C domains are extremely fine dispersed and property originated from the molecule structure of the polysilane. Furthermore the relation between molecular structure of the polysilane and SiC is described. The investigations show patterns corresponding to the β-SiC polytype. -(MARTIN, H.-P.; IRMER, G.; MUELLER, E.; J. Eur. Ceram. Soc. 18 (1998) 3, 193-199; Inst. Keram. Werkst.,
