Abstract
- Abstract: Titanium silicon carbide (Ti3SiC2) ceramic was synthesized by in-situ reaction of metal titanium and polycarbosilane. Reaction mechanisms which lead to the formation of Ti3SiC2 were suggested on the basis of XRD analysis. The content of Ti3SiC2 reached 93% in products obtained from heating the Ti/polycarbosilane green compact at 1400 °C in Ar. The morphology and compositions of the products were examined by SEM equipped with EDX. The typical laminate structure of Ti3SiC2 particles with 1–4 μm in thickness and 4–15 μm in length was observed. EDX results showed that the atomic ratio of Ti:Si:C of grains is close to 3:1:2, which agrees with Ti3SiC2 composition. [Copyright &y& Elsevier]
