metallurgical calcium metal production

US4539194A - Method for production of pure silicon

Pure silicon metal is produced from a silicon metal which contains 1-10% Ca and which is cast into molds with relatively slow rate of cooling. The cast metal is pre-crushed and thereupon subjected to a purifiion process consisting of two leaching steps where in the first leaching step there is employed an aqueous solution of FeCl 3 or FeCl 3 +HCl which causes a disintegration of the metal.

The Properties, History, Production and Uses of Silicon Metal

Aug 15, 2019· Metallurgical silicon is classified by the impurity levels of iron, aluminum, and calcium present in the alloy. For example, 553 silicon metal contains less than 0.5 percent of each iron and aluminum, and less than 0.3 percent calcium.

Metallurgical Grade Silicon (MG-Si) for Research & Production

The silicon is then treated to remove impurities such as calcium and aluminum, leaving behind what is known as metallurgical silicon. The metal chloride is evaporated at high temperatures and the chlorine gas therefore reacts to a high degree with the silicon and other metals in the substrate and with other materials.
