一、碳元素有第三种结晶形式吗? 几个世纪以来,化学教科书总是说碳元素有两种同素异构体——石墨和金刚石。两者虽然都是由碳组成,但因其原子的排列和原子之间的结合不同,性质也截然不同。 除了石墨和金刚石之外,是否还存在碳的第三种同素异构体呢?这是人们普遍关心的问题。1970年,日本著名科学家小泽预测:碳的第三种同素异构体应该是自然界中普遍存在的
Is there a third crystalline form of carbon? For centuries, chemistry textbooks have always said that carbon has two isomeric forms—graphite and diamond. Although both are composed of carbon, their properties are also very different because of the arrangement of atoms and the combination of atoms. In addition to graphite and diamond, is there a third allotrope of carbon? This is a common concern. In 1970, the famous Japanese scientist Ozawa predicted that the third allotrope of carbon should be ubiquitous in nature.
