A chemically modified polycarbosilane (PC) containing organofluoric groups (PCOCF) has been synthesized from PC and fluoroalkylmethyldimethoxysilane. PCOCF acts as an efficient compaction binder for SiC powders and as a coating material with excellen

If electrical power is transmitted by a power cable made of SiC fiber-reinforced aluminum, Al atoms diffuse into the reinforcement fiber at the transmission temperature. In this study, the diffusion coefficients of Al atoms in Hi-NicalonTM/Al system
