Another example of this acid attack is reported by LI et al [8] where a severe corrosion issue of cement-based structures by sulfuric acid was observed... testing procedure. In addition, it is environmentally significant to carry out this research as the silica fume is the waste from the metal and alloy production industry, while nano- silica can......

中镍主要以铁为载体,并以Fe-Ni形式生成. 2.3 钛冶金 LI等[62-63]采用H2,CO混合气体,对钒钛磁铁矿球团进行还原,并分析反应过程的动力学,发现:随着还原温度,V(H2)/V(CO)比例的升高以及球团粒径减小,金属总还原率呈升高趋势；还原反应表面活化能为60.78 kJ/mol,反应过程初始阶段由表面化学反应控制,末尾阶段则由化学反应与内扩散环节联合控制；对含FeO... ℃条件下还原钛铁矿,反应初始的1 h时间内,低H2压力下还原反应速率更高,随着反应的进行,则需要提高H2压力才能保持与初始相当的还原反应速率. ZHAGN等[66]采用H2辅助镁热还原TiO2制备了钛金属粉末.由于钛对氧具有极强的亲和力,Mg难以直接还原TiO2,而高温条件下Ti-H-O固溶体稳定性低于Ti-O固溶体,因此,可采用H2气氛增强Mg与Ti-O反应的热力学驱动力,通过镁的进一步脱氧作用......
