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 'gallium, semiconductor-grade', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. gallium, semiconductor-grade' is an inorganic substance with a CAS no. : 007440-55-3. It is called 'gallium' under IUPAC naming and its molecular formula is: Ga. It is solid under normal conditions of temperature and pressure with no information available about its odour. The substance is produced and purified to 99.9999% On a consumer level, is used in the following products: Electrical and electronic products On industrial sites, the substance is used for the manufacture of products in the following sectors: Hardener/alloy agent for secondary aluminum processing, high purity gallium is combined with other elements through thin film deposition onto substrate wafers to make LED's, transistors, etc., also combined with other high purity substances like arsenic or nitrides and a boule (crystal) is grown in a furnace operation. These are sliced into thin wafers to be used as substrates for semi-conducting products. This market is supplied by the following activities with the given share: gallium production, semiconductor-grade, GLO: 1.0 generalComment of gallium production, semiconductor-grade (GLO): Production of gallium from Bayer-liquor, purification to 99.9999% (6N) [This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.]
