What is the difference between ferrosilicon, ferrosilicon powder and silica ash? Let's take a look:

Ferrosilicon is made of coke, steel chips, quartz (or silica) as raw materials, smelted with an electric furnace. Silicon and oxygen are easily synthesized into silicon dioxide. Therefore, ferrosilicon is often used in steelmaking as a deoxidizer, and because SIO2 is generated to release a lot of heat, it is also beneficial to increase the temperature of molten steel while deoxidizing. Ferrosilicon as an alloying element additive. Widely used in low-alloy structural steel, bonded steel, spring steel, bearing steel, heat-resistant steel and electrical silicon steel, in addition to ferrosilicon production and chemical industry, commonly used as a reducing agent. The silicon content is 95% 99%. Pure silicon is commonly used to manufacture monocrystalline silicon or formulate non-ferrous metal alloys.

Ferrosilicon powder: basically the same as the composition of ferrosilicon, commonly known as 75#, 72#, 70#, 65#, 60# ferrosilicon powder.

Silica ash: is a by-product of the production of ferrosilicon.
