“钻石是世间最硬的物质”。千百年来,一代一代相传,形成根深蒂固的传统定论。可是这一定论正受到挑战,一种比金钢石(钻石)还要硬的物质已经问世,这使全世界科学界和工程技术界人士惊喜不已。 新材料的发现 最近德国联邦研究和技术部组织科学家研讨后,提出21世纪初的关键技术有:新材料技术、微电子技术、纳米技术、光子学、显微系统技术、软件技术、纳米电子学、细胞生物技术等。可以看出,新材料技术在21世纪初将是首当其冲的关键技术,可见其重要性。有人指出,21世纪是材料科学世纪。近年来,材料科学技术确实有很多重大的新进展。突出事件有:金钢石低压合成技术、高温超导体、多孔硅材料、富勒碳和纳米材料 “Diamonds are the hardest substance in the world.” For centuries, generations passed from generation to generation, forming a deeply rooted tradition. However, this argument is being challenged. A material harder than diamonds (diamonds) has come into being, which has surprised the scientific community and engineers in the world. The discovery of new materials After the recent German Federal Ministry of Research and Technology organized scientists to discuss, proposed the early 21st century key technologies are: new materials technology, microelectronics, nanotechnology, photonics, microscopy, software technology, nanoelectronics , Cell biology technology and so on. It can be seen that the new material technology will be the first and foremost key technology in the early 21st century, showing its importance. It was pointed out that the 21st century is the century of materials science. In recent years, material science and technology do have many significant new developments. Prominent events are: diamond low-pressure synthesis technology, high temperature superconductors, porous silicon materials, fullerenes and nanomaterials
