The graphite crucibles were prepared with flake graphite, silicon carbide, silica and kaolin. The influence factors on the properties of samples were investigated. The results show that, with the increase of the silicon carbide content, the volume density of samples increases, the porosity decreases, the weight loss rate of the sample reduces and the antioxidant activity improves. Elevating the oxidation temperature and prolonging the oxidation time increase the weight loss rate of the sample, decrease the antioxidant activity. The microstructure analysis show that the compactness of the samples rises when the silicon carbide content and the sintering temperature increase. The numerical simulation results show that the electromagnetic force and the flow distribution induced by the melt surface are significantly different…
Although the density of carbon fiber is lower than that of aluminum, its strength is higher than that of steel. Carbon fiber is not only the inherent "hard" characteristic of carbon materials, but also the machinability of textile fiber. A carbon fiber woven graphite felt has good conductivity, mechanical properties, electrochemical reaction activity, acid resistance, corrosion resistance and oxidation resistance, is a good electrode material, compared with metal, graphite powder and various electrode materials, more suitable for the electrode storage battery. At present, the domestic production of graphite felt is mainly used to make thermal insulation material, and its conductivity and electrochemical activity can not meet the requirements of the use of battery electrode materials, therefore, the need for carbon…
