Details

Silicon Metal Powder Lab Grade

Silicon metal powder appears as a dark brown amorphous powder, has no odor, and is practically insoluble in Water at ambient conditions. However, it is soluble in molten Alkali Oxides and a mixture of Nitric-Hydrofluoric acids. It burns readily on exposure to heat or flames and may be difficult to extinguish with Water. It combines with Oxygen and other elements to form Silicates that constitute more than 25% of the Earth's crust. It is commonly produced on an industrial scale by Carbon reduction of Silica in an electric arc furnace followed by purification. Chemically pure or Laboratory reagents are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity.
