Processing of Highly Porous, Open-Cell, Microcellular Silicon Carbide Ceramics by Expansion Method Using Expandable Microspheres. Journal of the Ceramic Society of Japan 2006 , 114 (1330) , 549-553.
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.

Tungsten Carbide (WC) is a tough, high-density ceramic often used in severe service appliions. Tungsten carbides are commonly known for use in high-quality tooling inserts. Due to its high-temperature tolerance, stiffness, hardness, and flexural strength allow tungsten carbide is also used in other harsh appliions like mechanical seals and downhole drilling components.
Coustion Synthesis of Silicon Carbide 391 reaction rate throughout the mixture. Thus, the SHS mode can be considered as a well-organized wave-like propagation of the exothermic chemical reaction through a heterogeneous medium, which leads to
Silicon carbide (SiC) pipes are manufactured at CeramTec’s Sumperk site for a variety of different industrial uses. Pipes manufactured from ROCAR ® silicon carbide ceramics are hard, wear-resistant and possess excellent thermal conductivity properties. Read more
Arrays of oriented silicon carbide (SiC) nanowires are synthesized by reacting stable carbon nanotubes—which act as both template and reagent—with SiO. Field emission measurements on the nanowires indie that the arrays are excellent field emitters, technologically useful field emission current densities being produced at very low electric fields.

1979/5/15· What is claimed is: 1. A method for manufacturing a reaction bonded silicon carbide body comprising: heating, in a vacuum or an inert atmosphere, to at least the melting temperature of elemental silicon, a porous compact consisting essentially of a uniform mixture
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).
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 .
Silicon Carbide (SiC) is a wide-band-gap semiconductor biocompatible material that has the potential to advance advanced biomedical appliions. SiC devices offer higher power densities and lower energy losses, enabling lighter, more compact and higher
