Abstract:
A method for producing an SiC preform having a high volume fraction, comprising the steps of:mixing SiC particles of different particle sizes each selected from a range of 0.2 to 48 &mgr;m with an organic binder, an inorganic binder, an aggregating agent, and distilled water, thereby producing a mixture, and stirring the mixture in accordance with a ball milling process, thereby producing a slurry containing the SiC particles; pouring the slurry containing the SiC particles into a mold having upper and lower molds respectively provided with absorbent bodies, and squeezing the slurry in the mold, thereby reducing a residual moisture content of the slurry; completely drying the slurry reduced in residual moisture content, thereby producing an SiC preform; and calcinating the SiC preform.
