PREPARING METHOD OF CARBON/CERAMIC COMPOSITE

摘要

A carbon-ceramics composite is produced by (1) adding pitch system (isotropic and/or anisotropic) 10-40 wt.% with more than 300 deg.C of melting temperature as a carbon source, into a blast furnace water granulating slag 60-90 wt.% as a ceramic source, (the size of the mixed powder of the above pitch and slag is less than 0.074 mm), (2) pressure molding under the range of 100-500 kg/cm2 G, (3) heating the above molding material at a rate of less than 10 deg.C/ min in inert gas atmosphere, and (4) sintering the above (3) for 1 hour in the temperature range of 1,050-1,150 deg.C.
