Simple history of ferrosilicon development 

Learn what the simple history of ferrosilicon development is:

In 1810 Bergilius made ferrosilicon. In the experiment, he smelted iron filings, quartz and pine charcoal black in a calcination furnace to obtain silicon 2. 2% to 9.3% low-grade ferrosilicon;

In 1875, Pulsell successfully produced 10% to 18% silicon iron containing silicon in a blast furnace;

In 1899, Di Sharmo and others made electric furnace ferrosilicon in the electric furnace of the Holkumrock factory in the United States, containing 25% to 50% silicon;

Around 1903, Cádal produced 75% of the ferrosilicon containing silicon in an electric furnace according to the Disalmo method, which continues to this day. Now not only can produce a variety of silicon-containing ferrosilicon, but also the content of impurities is low, can meet the needs of industrial development.
