Preparation of RBSC Green Bodies by Gel-Casting
In this paper,green bodies of RBSC were prepared through the gel-casting process.The effects of monomer concentration and ratio of MBAM to AM on the strength and microstructure of the green bodies were studied.When the monomer content increased from 10wt% to 20wt %(relative to water in the slurry),the flexural strength increases efficiency.However,the flexural strength decreases when the monomer content was above 20wt%.Similarly,when the ratio of MBAM to AM increased from 1/19 to 1/9,it had the same effects on the flexural strength of green bodies.It was found that silicon carbide particles were packaged by the carbon particles with gel.When the monomer content was 20wt% and the ratio of MBAM to AM was 1/9,the green body showed the best homogeneous microstructures and its flexural strength achieved 8MPa.
