Silicon is one of the semi-metals, formerly known as "silicon". The melting point is 1420°C and the density is 2.34g/cm3. Hard and brittle. Insoluble in acid at room temperature, easily soluble in alkali. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.

Description

Silicon is extremely rich in resources in the earth's crust, second only to oxygen, accounting for more than a quarter of the total weight of the earth's crust, and exists in the form of silicon dioxide or silicate. The purest silicon mineral is quartz or silica. Silicon has two allotropes: one is dark brown amorphous powder, which is active and can burn in air; the other is stable crystal (crystalline silicon).

Generally, silica and quartz are used for glass and other building materials, and high-quality quartz is used for making alloys, metals and single crystals

Ultra-pure silicon (the impurity is no more than a few atoms per thousand atoms) is the most important semiconductor material, which is widely used in computers, microwave communications, optical fiber communications, and solar power generation. Semiconductor silicon materials are developing rapidly. The annual consumption of monocrystalline silicon exceeds 2,500 tons, and the consumption of silicon wafers is 2.5 billion square inches.

The research and production of silicon materials in my country has also made great progress. The single crystal with a diameter of less than 3 inches has reached the international level, and the cutting, grinding, and polishing processes and equipment have been established, but the overall level still has a certain gap with the international level. Therefore, my country's ultra-pure silicon has great development potential and a long way to go.

Why is the present era called the Silicon Age? At the 7th International Conference on Crystalline Silicon Production, scientists called the present era the Silicon Age. Why is silicon mentioned to such a high status? This is because the world today is moving from the industrial age to the information age.

In the industrial age, steel was the leader, so the amount of steel produced marks a country's economic and military strength. In the information age, the leader is the semiconductor material - silicon. There are many types of semiconductor materials, but there are not many types of industrial production, mainly silicon, germanium, gallium arsenide, and gallium phosphide, among which silicon accounts for about 90% of the total output of semiconductor materials. This is why people refer to the current era as the Silicon Age.

The classification of metal silicon is usually classified according to the content of three main impurities of iron, aluminum and calcium contained in metal silicon. According to the content of iron, aluminum and calcium in metal silicon, metal silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 and so on.
