通过在1000至2800° C的温度下加热具有1.6重量%硼的生焦炭压块来制备含硼硬型（HT）碳。测量了掺硼高温碳材料的一些物理和机械性能，并与无硼高温碳材料进行了比较。经证实，硼在1400° C的相对低的温度下进入HT碳，并在高于1800° C的热处理期间增强压坯的致密化过程。硼的加入导致高温炭的杨氏模量和热导率增加，硬度和电导率降低。的影响进行了讨论，并与可石墨化碳。
The boron-containing hard-type (HT) carbons were prepared by heating the raw coke compacts with 1.6 wt% boron at temperatures ranging from 1000 to 2800° C. Some physical and mechanical properties of boron-doped HT carbons have been measured and compared with those for boron-free materials. It was confirmed that the boron enters the HT carbon at a relatively low temperature of 1400° C and enhances the densification process of compacts during heat-treatment above 1800° C. The addition of boron caused increases in Young's modulus and thermal conductivity, and decreases in hardness and electrical conductivity of HT carbons. The effects are discussed, and compared with those for graphitizable carbons.
