The micro-structure and properties of charcoal and SiC ceramics derived from bamboo

以毛竹、印度莉竹为原料,在氮气氛中炭化制得竹炭,然后于1450℃下采用熔融Si渗透技术制得SiC陶瓷材料.借助SEM、XRD、X射线能谱仪、TGA和万能力学试验机等测试手段对竹炭和SiC陶瓷材料的微观构造、物相构成、材料的微区成分、力学特性及竹材的热失重行为进行了分析.结果表明:竹炭及其SiC陶瓷材料都继承了竹材的各向异性和微观构造特征;竹基SiC陶瓷是一种包含单质Si、C和SiC多相成分的复合材料;由两种竹材制备的竹炭及其SiC材料在微观构造、相组成和抗压力学性能上表现出一定的差异性.
