Pure Silicon Metal Grade 441
Pure Silicon Metal Grade 441 Description
Since silicon is plentiful and comes in a variety of forms, its applications are obvious. Polycrystalline silicon is the newest application of silicon used in wafer form. It is mainly used in thin-film solar cells and photovoltaic systems as a semiconductor. It is also used as a power transistor and semiconductor in the general field of electronics.
Our metallurgical silicon (Si ≥98.5-99.99%) meets the most stringent international standards, including ISO 9001 certification and industry specifications for applications in aluminum alloys, semiconductors, solar cells and silicones. Rigorous testing at every stage of production – from raw material procurement to final packaging – ensures consistent batch composition, low impurity levels (Fe, Al, Ca) and optimal particle size distribution to meet your requirements.
