High Purity Silicon Metal Granule 98.5% 99.99%
Description
Silicon metal powder is a silvery gray or dark gray powder with a metallic luster. This versatile material is characterized by a high melting point, excellent heat resistance, high electrical resistivity and resistance to oxidation. It is an important ingredient in the production of a wide range of electronic components and an additive in the melting of many different types of metals and metal products.

Application
Metallurgical Industry: Silicon metal is used as an alloying agent in the production of aluminum alloys, stainless steels, and other metal alloys. It enhances the properties of these materials, such as strength, hardness, and corrosion resistance.
Chemical Industry: It's used in the production of various chemicals, including silicones, silanes, and other silicon-based compounds.
Electronic Industry: Silicon metal is used as a raw material for producing semiconductor devices, such as transistors and diodes.
Packing & Delivery
1.Single layer packaging bag
2.Double layer packaging bag
3.Selective lamination
4.Binding method of straps:
(1) Bottom crisscross method
(2) fixed by surrounding item from all sides.
5.Standard capacity: 1 ton per bag. (100kg/200kg/250kg/500kg small bags can also be used for packaging. Using small bags incurs additional costs)
6.Palletization: one bag per pallet or two bags per pallet(charged in palletization ).
