把硅定义为“金属硅”是不合适的,事实上,硅是非金属性的,其性质与金属大不相同。为了了解在各种用途中硅的性能,必须了解其结构,尤其应该刻画出进入硅中所聚集的各种杂质相。对于冶金级硅的应用来说,杂质起着非常重要的作用。 Silicon is defined as “silicon metal” is not appropriate, in fact, silicon is non-metallic, its nature and metal is very different. In order to understand the performance of silicon in various applications, one must understand its structure, and in particular, describe the various impurity phases that accumulate in the silicon. Impurities play a very important role for metallurgical grade silicon applications.
