Abstract
Rice hull, which is one of the agricultural by-products in Japan, is required to utilize for the industrial resources from a viewpoint of recycling. The rice hull silica carbon (RHS carbon) is manufactured by impregnating a phenol resin into the rice hull, and then carbonizing in nitrogen gas atmosphere at high temperatures. The RHS carbon has the natural porous structure that is originated from the natural structure of the rice hull. In this study, pretreatment and kneading processes were added in the making process of the RHS carbon to improve the mechanical properties. The inserted processes achieved the uniform impregnation of the phenol resin into the porous structure, and improved the mechanical strengths and the distribution of them.
