摘要：
A high pure molybdenum disilicide was prepared by using the "chemical oven" enhanced self-propagating combustion method. The mixtures of Si and Ti were ignited as chemical oven. Ammonium chloride was added to the mixed powders to control the propagation rate of combustion. The compostion of product was detected by X-ray diffraction (XRD) and X-fluorescence analysis. Results show the molybdenum disilicide product is single phase with trace impurities. Scanning electron microscopy (SEM) photos show the product by chemical oven self-propating high temperature synthesis (SHS) method is more homogeneous than the product by normal SHS method.
