DESCRIPTION
Silicon metal 2202 also known as crystalline silicon or industrial silicon, is mainly used as a non-ferro alloy additive. Silicon metal is produced by smelting quartz and coke in an electric heating furnace. The content of silicon is about 98% (in recent years, 99.99% is also contained in silicon metal). Other impurities are iron, aluminum and calcium.
The size of silicon metal grade 2202 is 10-100mm or other sizes as customer’s request. The standard package of 1 ton/bag.
