Microporous Ceramics Made by Silicon Carbide Whiskers


Article Preview

A new method for preparing microporous ceramics by the silicon carbide whiskers was studied in this paper. The physical and chemical properties and the microstructure of the microporous ceramics were tested, while some influencing factors for the product, such as the amount of sintering aids and sintering temperature, were discussed. The results suggest that the apparent porosity of the microporous ceramics is 55.7-59.8% and the flexural strength is 127-176MPa. The pore distribution of the microporous ceramics is uniformity and the diameter of the pore ranges between 0.5μm and 7μm. The porosity and pore size of the microporous ceramic can be controlled by adjusting the sintering temperature and the amount of sintering aids.
