Recently we found in our experiments that this reaction can proceed at a high speed by catalyzing with HBr at room temperature, producing UF<sub>4</sub> and other products. In this note the HBr-catalyzed reaction of UF<sub>6</sub>+SiH<sub>4</sub> and the kinetic mechanism of the catalyzed reaction are investigated. 1 Experimental UF<sub>6</sub> gas, produced by the 404th Factory of Nuclear Industry Corporation, was vacuum-distilled and cold-trapped several times at dry ice temperature （-78℃） in a metal vacu-展开更多
