Silicon technical is made in the form of pieces by the sizes of 0-2 mm, 2-10 mm, 10-60 mm, 60 - 100 mm purity of 98 - 99%. With the content of impurity: gland - 0,4 - 0,7%, aluminum - 0,3 - 0,7%, calcium - 0,01 - 0,3%.

Scope: silicon of technical purity is used in ferrous and nonferrous metallurgy for receiving alloys on not an iron basis (alpax, etc.), an alloying (siliceous there were also alloys applied in electric equipment) and raskisleniye became also alloys (removal of oxygen), production of silicides, etc. Technical silicon is raw materials for production of purer polycrystalline silicon and a basis for the hi-tech industry. Silicon is and photo cells for solar batteries, and semiconductors for computers, and much, many other.
