Producing metallurgical grade silicon is achieved by reacting highly pure silicon with wood or charcoal in an electric arc furnace. The steel and aluminum industries are good examples of the metallurgical industry. Metallurgical grade silicon is a crucial stepping stone in the refining process of silicon metal. It is used extensively in ...
· silicon dioxide is found as huge deposits of quartzite or quartz sand. Moreover, many rocks contain quartz crystals. Therefore, it can be concluded that the resources of silicon are virtually unlimited (although purity varies considerably). The main applications of silicon are as follows: deoxidation and alloying of steel

· Aluminium alloys are lighter and more resistant to corrosion than carbon-steel and can be made by addition of metals such as copper, zinc, magnesium, manganese as well as silicon. Adding Silicon Metal to aluminium alloys makes them strong and light. As a result they are increasingly used in the automotive industry to replace heavier cast iron ...
In 3 patients, the stone was formed in the left kidney. Bilateral renal stones were found in 2 patients. In 2 patients, they were removed from the left ureter and in 2 patients they were found in the bladder. The size of the stones varied between 2 mm and 3 cm, the weight from 8 mg to 3.6 g. The silica stone is of a relatively low radio density.
Elemental silicon (Si), after oxygen, is the second most abundant element in the earth's crust, which is mainly composed of silicates. Si is not considered essential for plant growth and development, however, increasing evidence in the literature shows that this metalloid is beneficial to plants, especially under stress conditions. Indeed Si alleviates the toxic …
· This demand of lighter and more economical material has triggered a growth in Silicon metal consumption by aluminum manufacturers. That said, silicon compounds are …
Silicon-aluminum alloys tend to have relatively low strength and ductility, so other metals, especially magnesium and copper, are often added to improve strength. In the chemicals industry, silicon metal is the starting point for the production of silianes, silicones, fumed silica, and semiconductor-grade silicon.
