Preparation and Characteristic of Porous SiC Foamed Ceramics

Abstract:

Porous SiC foamed ceramics used raw material of SiC were prepared by adjusting slurry viscosity at 1400°C. Formed technology was dipping organic precursors. The result showed that the section of the sample presents three-dimensional net structure, wall of hole thickness is proper, the distribution of the hole are homogeneous, and have high porosity, apertures are small than 30 μm, the main crystal appearance is SiC. The strength of samples is been improved by dealing organic precursors. The slurry on the ribs is been increased.
