Abstract: Traditional methods to fabricate high-performance carbon and graphite materials is a high energy-consumptive and long process.Process by gelcasting was tried to fabricate high-performance graphite materials in this paper.The effects of dispersant content,pH,organic monomer content,and graphite solid loading on the slurry viscosity were discussed.The flexural strength and microstructure of the green body were analyzed.The results revealed that the microstructure and mechanical properties of the graphite green body fabricated by gelcasting were far superior to that fabricated by traditional mold pressing.
