近几年来的理论研究和实验表明,高压下元素可以形成经典化学中不可能存在的新化合物。日前从北京高压科学研究中心获悉,该中心研究员李阔与香港大学教授陈粤合作,首次合成了一种违背常见化合价的新型化合物Sn3Se4。该化合物具有金属性,在低温下会转变为超导体,并可能具有更好的物理性能。相关研究结果发表在3月28日出版的世界物理学 In recent years, theoretical studies and experiments show that the elements under high pressure can form new compounds that can not exist in classical chemistry. Recently learned from the Beijing High Voltage Research Center, Li Kuo, a researcher at the center, and Chen Yue, a professor at the University of Hong Kong, collaborated for the first time to synthesize Sn3Se4, a new chemical compound that violates common valences. The compound is metallic, transforms into a superconductor at low temperatures, and may have better physical properties. Relevant research results published in the March 28 world physics
