Description: technologyComment of silicon production, electronics grade (DE, RoW): In practice, EG-silicon is a product from complex chemical production plants. The conventional route for production of EG-silicon comprises three process steps: 1) the MG-silicon is converted into a gas, either trichlorosilane (SiHCl3) or silane (SiH4), 2) this gas is purified by means of distillation, 3) silicon in solid form is deposited in a Siemens reactor.

Comment: This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant. This is the market for 'silicon, electronics grade', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. silicon, electronics grade' is an inorganic substance with a CAS no. : 007440-21-3. It is called 'silicon' under IUPAC naming and its molecular formula is: Si. It is solid under normal conditions of temperature and pressure with no information available about its odour. The substance is modelled with >98% purity There is no publicly available information about the consumption of this substance on a consumer level. On industrial sites, the substance is used for the manufacture of products in the following sectors: electronics This market is supplied by the following activities with the given share: silicon production, electronics grade, DE: 0.5 silicon production, electronics grade, RoW: 0.5 generalComment of silicon production, electronics grade (DE, RoW): This dataset represents the multi-output process that delivers the co-products 'silicon, electronics grade' (EG-silicon), 'silicon, solar grade' and 'silicon tetrachloride'. EG-silicon is mainly used for the production of semiconductors in electronics. This dataset is based on literature data. References: Jungbluth N., Stucki M, and Frischknecht R. (2009) Photovoltaics.
