碳化硼在吸收材料中的地位及其与核应用有关的基本性能

The position of boron carbide in neutron absorbing materials and its properties relation to nuclear applications

对碳化硼与其它材料的中子吸收截面、吸收效率、价格进行了比较,综述了作为吸收材料的碳化硼在世界核反应堆中的地位,综述了影响碳化硼核应用的有关性能(均相区范围、热导率、比热容、热膨胀系数)的研究结果,并与报道的实验数据进行了校验,讨论了碳化硼的抗水腐蚀能力。

A comparison of boron carbide with other materials on the cross section, neutron absorbing efficiency and price was commented. As an absorbing material the portion of boron carbide in nuclear reactor in the world was summed up. The other influencing properties on nuclear application such as phase homogeneity range, thermal conductivity, specific thermal capacity, and thermal expansion coefficient were analysed, comparing with reported experimental data.
