The flexural strengths and oxidative resistant properties of the ceramics derived from polycarbosilane and active fillers (Ti, TiH 2, TiB 2, Cr, and CrSi 2) were measured and characterized. The introduction of active fillers enhances slightly the flexural strengths, and further densification is r...

The pyrolytic process of polycarbosilane (PCS) with active fillers (Ti, TiH 2, TiB 2, Cr, CrSi 2) is investigated. The ceramic yields with active fillers reach over 100% in N 2 atmosphere, and no shrinkage occurs when 12vol% Ti, or 4vol% Cr, or 3vol% CrSi 2 is added into PCS. XRD patterns indic...
