S. Ueno et al., CRYSTALLIZATION AND OXIDATION RESISTANCE OF CARBON CERAMICS COMPOSITES PREPARED FROM PHENOLIC RESIN, B(OH)(3) AND AL CHELATE COMPOUND/, Nippon Seramikkusu Kyokai gakujutsu ronbunshi, 106(11), 1998, pp. 1104-1109
To improve the oxidation resistance of carbon, carbon/ceramics composi
tes were prepared from phenolic resin, ethyl acetoacetate aluminum di-
isopropylate (ALCH) and boric acid by carbonization at 1300 degrees C,
1600 degrees C and 1900 degrees C. Attention was focused on the oxida
tion resistance and crystallization of the carbon/ceramics composites.
The result showed that carbon/ceramics composites with 9 mass% of Al2
O3: B (OH)(3)=1 : 1, 1 : 2 and 0 : 1 had an optimum oxidation resistan
ce, when heated at 1600 degrees C. Samples containing ALCH were also h
eated to 1900 degrees C and crystallization of carbon was observed.
