Silicon Metal to produce organic-Si

"Metal Silicon" (China also known as industrial silicon) is a commodity name appeared in the mid-1960s. Its emergence is related to the rise of the semiconductor industry. The common international practice is to divide commercial silicon into metallic silicon and semiconducting silicon.

Silicon metal is made of quartz and coke in electric furnace smelting products, the main component of the content of silicon is about 98% (containing Si content of 99.99% is also included in the metal silicon), the rest of the impurities of iron, aluminum, calcium, etc. .

Semiconductor Silicon High-purity silicon metal used to make semiconductor devices. Is based on polycrystalline, single crystal form for sale, the former is cheap, the latter is expensive. Because of their different uses and divided into a variety of specifications.

• Usage: Mainly used to produce organic-Si in chemical industry and also can be applied to mechanical, chemical, alloys, electron, medicine industry, state defense etc.
• Size: 10-50mm.10-100mm etc.
• Packing: In plastic woven bags of 500kg or 1mt net each or in bulk, and also can be packed according to customer`s requirement.

• Specifications (%):

According to statistics, a total of about 500,000 tons of silicon metal were consumed worldwide in 1985, of which about 60% was used for aluminum alloy, less than 30% for silicone, about 3% for semiconductors, and the rest used for Steel smelting and precision ceramics.
