Today's  focuses on a very common non-metallic element - silicon. It is a carbon group element in the third period of the periodic table.In 1811, French chemists first obtained impure amorphous silicon by heating potassium and silicon tetrafluoride, which can be obtained in a variety of ways. In the crust, it is the second most abundant element, which makes up 26.4 percent of the total mass of the crust, is second only to oxygen.

Tin

Today we're going to talk about the metal Tin (Sn). Tin is in the fifth period of the periodic table, the fourth group. The metal was known as early as the 4th century BC. But it was difficult to refine, so the price was higher.During the Bronze Age, tin was used as a strategic metal because tin-containing bronze was much stronger than pure copper. Tin is derived from minerals such as tin and sulfur.

Factory price to sell high purity polysilicon

Polysilicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooled conditions, the silicon atoms are arranged in a diamond lattice form into a plurality of crystal nuclei. If the crystal nuclei grow into crystal grains with different crystal orientations, the crystal grains are combined and crystallized into polycrystalline silicon.
