Metallic silicon's introduction

The melting point of metal silicon is an important physical property of metal silicon. With the increasing application of metal silicon in people's daily life and industrial production, various studies on metal silicon are of great significance. Understanding the melting point of metal silicon is conducive to mastering the various properties of metal silicon and making better use of metal silicon.

The melting point of metal silicon is 1410C, the boiling point is 2355C, the resistivity is 2140Ω.m, and the density is 2.33g/m3.

Metal silicon, also known as industrial silicon in my country, is a commodity name that appeared in the mid-1960s. Its emergence is related to the rise of the semiconductor industry. At present, the international common practice is to divide commodity silicon into metal silicon and semiconductor silicon. Metal silicon is a product smelted from quartz and coke in an electric furnace. The content of silicon, the main component of metal silicon, is about 98% (in recent years, 99.99% Si content is also included in metal silicon), so the melting point of metal silicon is similar to that of silicon. The remaining impurities are iron, aluminum, calcium, etc. Semiconductor silicon is a high-purity metal silicon used to make semiconductor devices. It is sold in the form of polycrystalline and single crystal, the former is cheap and the latter is expensive. Metallic silicon can be divided into various specifications according to its different phase properties (such as the melting point of metallic silicon) and its different uses.
