In the present work, 2-hydroxyethyl methacrylate(HEMA)-1,6-hexanediol diacrylate(HDDA) non-aqueous gelcasting system was adopted to prepare concentrated slurry of Mo/Cu powders. The effect of dispersant dosage, monomer content and solid loading on rheological behavior of slurry was studied. The effect of processing parameters such as monomer content, monomer/cross-linker ratio, initiator dosage, temperature on the gelation behavior and green bodies’s flexural strength was studied. Results show that, solid loading influence the viscosity of slurry the most, followed by dispersant dosage and monomer content. The flexural strength of green bodies increases with the increasing of monomer content and the decreasing of monomer/cross-linker ratio, initiator dosage has a relatively slightly effect. On the basis of these, the optimum processing parameters for Mo/Cu non-aqueous gelcasting are as follows: HEMA content is 25 vol.% ~ 30 vol.%, monomer/cross-linker ratio is 10:1 ~ 15:1, initiator dosage is 1.5 vol.% ~ 2.5 vol.%, and gelation temperature is 60_oC ~ 80_oC.
