ZSM-5 Coatings on β-SiC Monoliths: Possible New …

Structured zeolite/silicon carbide composites were succesfully synthesized by ZSM-5 coatings deposited on macroscopic β-SiC foams with medium surface area. A homogeneous coverage of the support (30 wt % zeolite) by ZSM-5 crystals, having 1 μm average size, was reached after a double-coating procedure.

Template‐Synthesized Porous Silicon Carbide as an

A facile method has been developed for the fabriion of porous silicon carbide (SiC) by means of sintering a mixture of SiC powder and carbon pellets at a relatively lower temperature, that is, 1450 °C, in air. The pore density and the total pore volume of the resulting porous SiC could be tuned by changing the initial SiC/C weight ratio.
