Disclosed is a method for manufacturing composite granules having a homogeneous particle distribution, comprising powders of multimodal particle size distribution and phenol resins, and a method for manufacturing green bodies having homogeneous microstructure without particle separation from the granules.

Method for manufacturing homogeneous green bodies from the powders of multimodal particle size distribution using centrifugal casting

A method and an apparatus for manufacturing a reaction bonded silicon carbide by the infiltration of molten metal by using a porous silicon carbide/carbon or carbon preform in which the molten metal is supplied to the carbon preform by capillary action through a pyro-carbon coated dense graphite feeder on which a transfer path of molten metal is defined from a molten metal supplier under an inert atmosphere, and a carbon woven fabric on which the carbon preform is placed transfers continuously the carbon preform at a constant speed and thereby infiltrates the carbon preform. The apparatus and method for manufacturing a reaction bonded silicon carbide which enable mass production of goods of various sizes and characteristics by continuously transferring the carbon preform on the carbon woven fabric and supplying the molten metal through the pyro-carbon coated graphite feeder.

A SiC whisker-reinforced ceramic composite is prepared by adding about 0.4 to 1.0% by weight of a nonionic polymer, polyvinylalcohol (PVA) to a heat-treated SiC whisker to obtain a SiC whisker slurry, mixing the SiC whisker slurry with a matrix slurry formed at about pH 4 followed by freeze-drying the resulting slurry mixture to produce granules having a uniform packing structure and hot pressing the granules.
