日本东洋碳素公司与美国加州大学共同开发出一种高级新材料,可用作磁聚变堆中接蚀等离子体的元件。新材料称为块状硼化石墨,属固溶相和碳化硼相组成的两相结构。固溶相中仅百分之几的硼溶解于石墨晶格间,而碳化硼相中含硼量高达80%。总体来看,新材料中硼浓度可控制在3—30%。这种材料在许多方面优于目前世界上所有聚变堆中用以接触等离子体的普通石墨,预期可用以改进等离子体性能。
Japan’s Toyo Carbon and the University of California jointly developed a high-level new material that can be used as a component of a plasma-fusion reactor plasma-eroded plasma. New material known as bulk graphite boride, solid solution phase and boron carbide phase composed of two-phase structure. Only a few percent of the boron in the solid solution phase dissolves in the graphite lattice, while the amount of boron in the boron carbide phase is as high as 80%. Overall, the new material boron concentration can be controlled at 3-30%. This material is in many ways superior to the conventional graphite used to contact the plasma in all the fusion reactors in the world today and is expected to improve plasma performance.
