USES OF SILICON METAL:

There are two main applications for Silicon Metal:

1.As an alloying element for aluminium alloys for casting and extrusions.

2.As the basic raw material for silicones produced by the chemical industry.

 

 

PRODUCTION OF SILICON METAL:

 Preparing low boron

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

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

Melting low boron

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 low boron 

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

Cooling low boron

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

Crushing  low boron

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.

PRICE OF SILICON METAL:

The main factors that affects the price:

1.Electric power price is the main cost of silicon metal production

2.The demand of silicone market is rigid

3.Under the influence of the prosperity of automobile manufactoring industry prosperity.

4.Silicon metal industry is highly positive related to the economic prosperity.

 

 5.Policy implications.
