Rice husk ash (RHA) is one of the industrial waste byproduct available abundantly in the world. In the present work, an attempt is made to incorporate the RHA particles in the molten aluminum A356.2 alloy. The RHA particles were added into the matrix melt by creating a vortex with the help of a mechanical stirrer and the melt temperature was maintained between 800 and 850 °C. Dry sliding wear experiments were performed in a pin on disc wear equipment against a chromium steel disc at 30 °C. Scanning electron microscopy is used to study the wear characteristics of the unreinforced Al alloy and the A356.2/RHA composites. From the experiments it is observed that the composites exhibit higher hardness and resistance to wear as compared to unreinforced Al alloy.

将V2O5, CeO2和CuO分散到提取自稻米壳的SBA-16上,考察了其催化CO氧化反应活性,并采用X射线衍射、扫描电镜、透射电镜、程序升温还原和紫外漫反射光谱对所制催化剂进行了表征。结果表明,掺杂CuO的介孔氧化硅是一种有前景的催化剂,其CO转化率可达98%以上。
