TECHNOLOGY PARAMETERS OF ULTRA-FINE β-SiC POWDER BY COMBUSTION SYNTHESIS

ZHANG Lifeng,YAN Qingzhi,SHEN Weiping,GE Changchun (Laboratory of Special Ceramics and Powder Metallurgy,University of Science and Technology Beijing,Beijing 100083,China)  
Ultra-fine β-SiC powder has been obtained by two methods,direct combustion synthesis and preheating combustion syn-thesis,in nitrogen atmosphere using Si,carbon,activated carbon as raw materials and teflon(-C2F4-)n as additive.The crystallites of combustion products measured by a scanning electron microscopy showed that they are global and the average diameters are about 100 nm.Pure and ultra-fine β-SiC powders can be obtained on direct combustion when the mass fraction(the same below)of additive is more than 5%.The theoretic preheating-temperature can decrease from 1 023 K to 673 K by decreasing the amount of additive to 2% and thus saving the cost.The same time,using activated carbon as substitution of carbon,the effect on combustion products of two batches of mole ratio of Si to active C with 1:1 and 1:1.25 was compared,it illustrated that the substitution of purer active C for carbon as raw material in preparing the β-SiC is possible.Three methods of preheating combustion synthesis,combustion synthesis in nitrogen atmosphere and chemical stimulation combustion synthesis were successfully combined,and the material introduce from pressed block to powdery spread,the ultra-fine β-SiC powders were fabricated through combustion synthesis in 60 L reactor with a single load of more than 1 kg materials.It makes the needs of pilot-plant.
