Silicon Metal Alloy
What are the properties and characteristics of chemical silicon?
1. The classification of metallic silicon is usually based on the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component.
Monocrystal Silicon
2. The main component of metallic silicon is silicon, so it has similar properties to silicon. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.
Monocrystalline Silicon Product Introduction
When the molten elemental silicon solidifies, the silicon atoms are arranged in a diamond lattice to form crystal nuclei, and the crystal nuclei grow into grains with the same crystal plane orientation to form single crystal silicon.
Monosilicon
The manufacturing of monocrystalline silicon materials goes through the following processes: quartz sand - metallurgical grade silicon - purification and refining - deposition of polycrystalline silicon ingots - monocrystalline silicon - silicon wafer cutting. Its main uses are as semiconductor materials and the use of solar photovoltaic power generation, heating, etc.

Polysilicon Related Knowledge
Polysilicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, the silicon atoms are arranged into multiple nuclei in the form of a diamond lattice. If the crystal nuclei grow into grains with different crystal orientations, the grains combine and crystallize into polysilicon.
Polycrystalline silicon can be used as raw material for pulling single crystal silicon. The difference between polycrystalline silicon and single crystal silicon is mainly reflected in the physical properties. For example, the anisotropy of mechanical properties, optical properties and thermal properties is far less obvious than that of single crystal silicon.
