Detailed description

Silicon Metal processed by excellent industrial silicon and including full varieties.

Used in electro, metallurgy and chemical industry. It is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, highresistivity and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in hi-tech industry.

Production of Silicon Metal:


Preparing

1.The raw materials(silicon dioxide,carbon materials) are weighed and then placed into the furnace through the top using the fumehood.

2.The lid of furnace,which contains electrodes,is placed into position.


Melting 

3.Electric current is passed through the electrodes to form an arc.The heat generated by this arc melts the material and results in the reaction of sand with carbon to form silicon and carbon monoxide.


Reducing w boron low phosphorus 

4.While the metal is in the molten state,it is treated with oxygen and air to reduce the amount of calciumand aluminum impurities.Depending on the grade,silicon metal contains 98.5-99.99%silicon with trace amounts of iron,calcium and aluminum.


Cooling 

5.The silicon is then tapped from the bottom of the furnace and cooled in large cast iron trays.


Crushing

6.After cooling,the metal is dumped from the mold into a truck,weighed and then dumped in the storage pile.Dumping the metal from the mold to the truck breaks it up sufficiently for storage.


Packaging 

7.Silicon metal is usually packaged in large sacks or wooden boxes.In powder form,silicon is packaged in plastic pails or paper bags.
