摘要
采用液相烧结法制备碳化硼陶瓷,初步对比考察了七组添加剂的助烧效果。结果显示,Al2O3,Y2O3以及Al2O3-Y2O3三组助剂效果明显,样品致密率可以达到95.0~96.2%,显微硬度达到3080 Kg/mm2以上。液相烧结对样品的断裂韧性没有明显改善作用。
Boron carbide ceramics were prepared by liquid phase sintering, and preliminary comparison examined the seven groups help burning effects of additives. Results show that： three groups additives of Al2O3, Y2O3 and Al2O3-Y2O3 affected remarkable. Sample density rate can reach 95.0 ~ 96.2%. Micro-hardness reached more than 3080 Kg/mm2. The liquid phase sintering had no effect on fracture toughness of samples.
