The effect of silicon on diffusion behavior of the carbide forming elements in Ni-Mo-Cr-Fe based corrosion-resistant alloy is studied by diffusion couple experiment. One group of diffusion couples are made of the alloy with a different silicon content, another group of diffusion couples are made of pure nickel and the alloy with different silicon content (0Si, 2Si). Two groups of alloys with

Silicon - The Environmental Literacy Council
Pure, elemental silicon does not occur in nature because it is highly reactive, tending to form compounds with other elements. It must be prepared artificially. One common method of preparing pure silicon (up to 98 percent purity) is by the reduction of silicone dioxide in the presence of carbon at high temperature (about 3000 degrees C; the melting point of silicon is 1412 degrees C):
Ferro Silicon Nitride for steel making is mainly for oriented silicon steel, stainless steel, heat-resistant steel, corrosion-resistant steel, alloy steel or other nitrides steel, like HRB400 rebar. Ferro Silicon Nitride is also an additive agent of making Cold rolled s.
