Metal Silicon For Metallurgy
What is Silicon Metal?
Silicon Metal processed by excellent industrial silicon and
including full varieties. Used in electro, metallurgy and chemical
industry. It is silver gray or dark gray powder with metallic
luster, which be of high melting point, good heat resistance, high
resistivity and superior oxidation resistance, it's called
"industrial glutamate", which is an essential basic raw material in
hi-tech industry.
It is an absolutely vital component in the production of a variety
of electronics components as well as an additive in the smelting of
many different types of metals and metal products.
Function
Our industrial silicon or silicon metal lumps come in irregularly
shaped chunks. These chunks are silvery gray or dark grey with a
metallic luster. These lumps are made up of quartz (SiO2) meaning
they can be processed to extract high purity silicon.

Particle size: 10-100mm,10- 50mm, 0-3mm, 2- 6mm and different granularities according to your needs.
Applications
1. Industrial silicon granule & powder is widely used in the
production of refractory materials and metallurgi. cal applications due to its high temperature resistance, wear
resistance, and oxidation resistance. Some examples of its
application are furnace walls, kilns, and kiln furniture
2. Used in organic chemicals: Silicon metal is used in
manufacturing a number of sorts of silicones, resins, and
lubricants.
3. In the metallurgical casting industry, industrial silicon metal is
an additive for nonferrous alloys and alloying agents in silicon
steel in order to greatly enhance the hardness of the finished
steel products. Silicon granules are also used as a metal reducing
agent for modern ceramic alloys, providing additional hardness and
heat resistance.
