It occurs in many plants and some animals. Pure silicon is a hard, dark gray solid with a metallic lustre and the same crystal structure as diamond. It is an extremely important semiconductor; doped (see dopant )with boron, phosphorus, or arsenic, it is used in various electronic circuit and switching devices, including computer chips, transistors, and diodes.

在很多植物中和某些动物中,也都含有硅的化合物。纯硅是一种质硬的深灰色固体,具有金属光泽,其晶体结构和金刚石相同。硅是一种非常重要的半导体;掺入硼、磷或砷后,可用于各种电子电路和开关器件,包括计算机芯片、晶体管和二极管。
