摘要
Abstract
High strength carbon materials were made with activated petroleum coke powder as the raw material ,coal pitch as the binder under different molding pressures and holding time . The mechanical properties of the samples were tested ,and SEM ,TG‐DTA ,XRD were analyzed .The interaction mecha‐nism of the raw materials and the binder was clarified .The results have shown that ,the properties of the roasted samples increase with the pressure holding time and the molding pressure .In the holding time of 20 min ,the molding pressure is 200 MPa ,the bulk density of the roasted sample reaches 1 .54 g/cm3 ,the compressive strength is 119 MPa and the flexural strength is 61 MPa .They are all better than the samples made without activated petroleum coke powder as the raw material .关键词
