摘要
Si-B-C ceramic composites were synthesized using SiB-6,B-4C,and phenolic resin as a carbon source by pressureless sintering in an Ar atmosphere.Then,the Si-B-C ceramic composites were fabricated to determine their potential for applications as high hardness and high temperature composites.The X-ray diffraction patterns of sintered bodies of SiB-6-B-4C with carbonized phenolic resin can be seen that SiB-6 and C changed to B-4C and SiC.In this study,it is obtained that carbonized phenolic resin is good addition material as a reaction material comparing to carbon powder at 1683 K for 1 h by pressureless sintering in an Ar atmosphere.
