Despite increasing processing power of systems, sequential programs have limitations to achieve corresponding performance gains. Parallelization of sequential programs can exploit the computation pote...
介孔空心球状WC微球结构与晶相形成机理（Structure and Crystal Phase Formation Mechanisms of Hollow Global Tungsten Carbide (WC) Microsphere with Mesoporosity）
介孔 空心球状 碳化钨 微球 形成机理
2010/8/18
采用喷雾干燥微球化处理-气固反应法制备了介孔空心球状WC微球，应用扫描电子显微镜(SEM)对微球的形貌变化进行了表征。结果表明，介孔空心球状结构是逐步形成的。其中，空心球状结构形成于前驱体微球化处理过程中，介孔结构形成于空心微球还原碳化过程中。在与样品制备工艺条件相同的情况下，采用原位X射线衍射技术(in situ XRD)对样品的晶相演变规律进行了监测。结果表明，样品在CO/CO2气氛中进行还...
