G eneral characteristics of silicon metal

Silicon metal is also known as metallurgical silicon or, most commonly, simply as silicon. Silicon itself is the eighth most abundant element in the universe, but it is rarely found in pure form on Earth. The US Chemical Abstracts Service (CAS) has given it the CAS number 7440-21-3. Silicon metal in its pure form is a grey, lustrous, metalloidal element with no odour. Its melting point and boiling point are very high. Metallic silicon starts melting at about 1,410°C. The boiling point is even higher and amounts to about 2,355°C. The water solubility of silicon metal is so low that it is considered to be insoluble in practice.

What is Silicon Metal used for?

Silicon Metal is usually used as employed in the chemicals industry for the manufacture of siloxanes and silicones. Silicon metal can also be used as essential material in the electronics and solar industries (silicon chips, semi-conductors,solar panels). It can also improve the already useful properties of aluminum such as castability, hardness and strength. Adding silicon metal to aluminium alloys makes them light and strong. So, they are increasingly used in the automotive industry. Used to replace heavier cast iron parts. Automotive parts such as engine blocks and tire rims are the most common cast aluminum silicon parts.

The application of Silicon Metal can be generalized as below:

● aluminium alloyant (e.g. high-strength aluminum alloys for the automotive industry).

● manufacture of siloxanes and silicones.

● primary input material in the manufacture of photovoltaic modules.

● production of electronic grade silicon.

● production of synthetic amorphous silica.

● other industrial applications.
