硅（Si），作为元素周期表中的第14号元素，是地球上除氧之外最丰富的元素。它在现代科技发展中扮演着至关重要的角色，尤其是在半导体工业中的应用。硅的原子序数为14，原子量为28.09，密度为2.33克/立方厘米，熔点为1414°C，沸点为3265°C。硅在自然界中主要以二氧化硅（SiO2）的形式存在，石英就是其最常见的矿物形态。
Silicon (Si), as the 14th element in the periodic table, is the most abundant element on earth except oxygen. It plays a vital role in the development of modern technology, especially in the semiconductor industry. Silicon has an atomic number of 14, an atomic weight of 28.09, a density of 2.33 g/cm3, a melting point of 1,414°C, and a boiling point of 3,265°C. Silicon exists in nature mainly in the form of silicon dioxide (SiO2), of which quartz is the most common mineral form.
硅的应用历史悠久，早在几千年前，人类就已经开始利用硅化合物。在古代，硅被用于制作陶瓷和琉璃，而到了公元前1世纪，人类首次成功制造出透明玻璃。17世纪，玻璃镜的发明推动了光学仪器的诞生，如望远镜和显微镜，极大地拓展了人类的视野和认知边界。
Silicon has a long history of use, and humans have been utilising silicon compounds for thousands of years. In ancient times, silicon was used to make ceramics and glazes, and in the 1st century B.C., humans first succeeded in making transparent glass. In the 17th century, the invention of glass mirrors led to the creation of optical instruments such as telescopes and microscopes, which dramatically expanded the boundaries of human vision and perception.
硅元素的发现是一段跨越多个世纪的科学探索史。1787年，法国化学家拉瓦锡首次意识到岩石中存在一种未知元素，他将其命名为“silice”。1823年，瑞典化学家贝采利乌斯通过加热氟硅酸钾与金属钾的混合物，成功提炼出了无定形硅，并通过反复清洗的方法将单质硅提纯，被誉为硅元素的发现者。
The discovery of the element silicon is a history of scientific exploration spanning many centuries. 1787, the French chemist Lavoisier first realised the existence of an unknown element in rocks, which he named "silice". 1823, the Swedish chemist Bezelius succeeded in refining amorphous silicon by heating a mixture of potassium fluosilicate and potassium metal. In 1823, the Swedish chemist Bezelius succeeded in refining amorphous silicon by heating a mixture of potassium fluosilicate and potassium metal, and purifying the monomaterial silicon by repeated washing, and is regarded as the discoverer of the element silicon.
硅的物理化学特性使其在现代科技中占据核心地位。硅既不像金属那样有良好的电导性和热导性，也不像非金属那样完全失去了金属的部分特征，具有介于金属和非金属之间的中间性质。硅的半导体性质使其成为理想的半导体材料，在电子设备中充当控制电流的介质和开关。硅的电导率会随着温度的升高而增加，这一独特现象为电子产品在高温环境下保持稳定性提供了重要保障。
The physicochemical properties of silicon have made it the centrepiece of modern science and technology. Silicon is neither as electrically nor thermally conductive as metals, nor does it completely lose some of the characteristics of metals as non-metals, having intermediate properties between metals and non-metals. The semiconducting nature of silicon makes it an ideal semiconductor material, acting as a medium and switch for controlling current in electronic devices. Silicon's conductivity increases with temperature, a unique phenomenon that provides an important safeguard for the stability of electronic products in high-temperature environments.
硅在半导体领域的应用广泛，包括单晶硅和多晶硅的制造，以及在芯片领域的高纯度要求。硅基集成电路的集成度越来越高，催生了从个人电脑到智能手机的移动终端设备繁荣。在可再生能源领域，高纯度的单晶硅和多晶硅是构建光伏电池的核心材料，通过光电效应将太阳光转化为电能。
Silicon is used in a wide range of semiconductor applications, including the fabrication of mono and polycrystalline silicon, as well as in chips where high purity is required. The increasing integration of silicon-based integrated circuits has spawned a boom in mobile terminal devices from personal computers to smartphones. In the field of renewable energy, high-purity mono and polycrystalline silicon are the core materials for building photovoltaic cells, which convert sunlight into electricity through the photovoltaic effect.
