卡宾碳──一种新的元素碳的同素异形体

CARBYNE──A NEW ALLOTROPE OF ELEMENTAL CARBON

卡宾碳 (carbyne)是元素碳的一种新的同素异形体 ,它广泛存在于各种地质体和碳化生物化石中。本文阐述了卡宾碳的一般性状和结构 ,以及赵氏碳 (choaite)和自然界中的卡宾碳 ,还简要阐述了卡宾碳的合成方法。卡宾碳还有许多疑难问题 ,合成足够大、足够纯和足够量的卡宾碳晶体 ,是推进卡宾碳研究的关键。

Carbyne is a new allotrope of elemental carbon with a linear structure, which can be found ubiguituously in terrestrial impact craters and carbonaceous materials of life remains. This paper expounds the general characters and structures of carbyne, chaoite and carbyne in nature, as well as the synthesis of carbyne. There are many unambiguous, also fascinating problems with carbyne. It is the key to produce carbyne crystals large enough in size, and amount and high enough in purity for promoting studies of carbyne.
