Synthesis of silicon carbide ceramics by novel microwave …

Studies of microwave processing of silicon carbide were then extended to x-aerogels, to probe whether the produced silicon carbide would mimic the porous microstructures offered by the precursor. This indeed resulted in the production of porous silicon carbide (in 15 minutes) and also sintered crystallites of micrometre sizes (after 3.5 minutes) whether MMC or SMC systems were employed.

Conversion of wooden structures into porous SiC with …

Synthesis of structured silicon carbide materials can be accomplished using wooden materials as the carbon source, with various silicon impregnation techniques. We have explored the low cost synthesis of SiC by impregnation of carbon from wood with SiO gas at high temperatures, which largely retains the structure of the starting wood (shape memory synthesis).

Melt Filtration

The best-known composite is SiSiC ceramics, which is produced by infiltration of silicon melt in porous bodies made of silicon carbide. The so-called LSI process (Liquid Silicon Infiltration) is also used to infiltrate porous bodies made of carbon or SiC fibres, whereby CMC components (Ceramic Matrix Composites) are produced .
