Fabrication and Properties of Si₃N₄-SiC-C Refractory Composites

Abstract:

Si3N4-SiC-C refractory composites were prepared under the condition of 1450°C × 3h with electrofoging anthracite, Si3N4, SiC as the raw material and the modification emulsified bitumen as the binder. The effects of the silicon and silica fine powder additives on the compressive strength of Si3N4- SiC-C refractory composites were studied. The results indicated that adding an appropriate ratio range of silicon or silica fine powder in the composites both can improve the compressive strength of the material.
