Silicon in the industrial production is indispensable, there are many silicon, with different metals have different roles, below we will give you a brief intro...

Used as deoxidation agent and alloy agent in steelmaking industry. In order to obtain the chemical composition of qualified steel and ensure the quality of steel, in the final stage of steelmaking must be deoxidation, the chemical affinity between silicon and oxygen is very large, so ferrosilicon is a stronger deoxidation agent for precipitation and diffusion deoxidation. Add a certain amount of silicon to the steel it can obviously improve the strength,Calcium Silicon Alloy hardness and elasticity of steel, thus, when smelting structural steels (including silicon 0.40-1.75%), tool steels (inc

Ferro silicon nitride is a Si3N4 as the main ingredient，along with free iron, no-nitride Ferro Silicon and small amounts of other components of the mixture. Ferro Silicon Nitride of refractory is a kind of gray powder,and it is the gray granular matter when used for steel making.

The less confirmed orders of Metal silicon terminal market

It is expected that the supply and demand of metal silicon will maintain the current level in the second half of 2019, and some brands will be in a state of oversupply.
