  • Apparatus for manufacturing reaction bonded silicon carbide
    Patent number: 6126749
    Abstract: 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.

  • Process for the preparation of SiC whisker-reinforced ceramic composite materials
    Patent number: 5656212
    Abstract: 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.
