Processing of Silicon Carbide-Mullite-Alumina Nanocomposites

Functionally Graded Alumina/Mullite Coatings for Protection of Silicon Carbide Ceramic Components from Corrosion

The deposition of carbon from ethylene in the presence of methyl-trichlorosilane or tetrachlorosilane is investigated in this study. Ex-periments are carried out in a hot-wall tubular reactor coupled to amicrobalance for continuous monitoring of the reaction rate. Thingraphite plates and refractory wires are employed as deposition sub-strates. The experimental results sh...

Superhydrophobic carbon nanotube/silicon carbide nanowire nanocomposites

a r t i c l e i n f o The composite film of carbon nanotubes and silicon carbide nanowires was synthesized directly on the silicon substrate by the catalyst-assisted method. The carbon nanotubes crimped together decorated with silicon carbide nanowires covering the whole substrate. The appropriate amount of aluminum powders is a crucial factor to achieve the composite film. The composite film e...

Mullite-alumina functionally gradient ceramics

Cracks free mullite-alumina Functionally Gradient Ceramics (FGC) have been obtained by sequential slip casting of Mullite-alumina slurries with diserent mullite/alumina ratios. These slurries were prepared with 65 % solids content and viscosities rangingpom 10 to 40 mPa.s. 7he presence of cracks perpendicular to the FGC layers have been attributed to residual stresses developed because of the m...
