Industrial waste silica preparation of silicon carbide ...

2017-2-25  The ball milling and cleaning of solid silicon waste from the organosilane industry, which originated from three different silicon sources, was used to obtain silicon containing copper, silicon containing FeSi 2, and pure silicon. The silicon source, GMs, and sucrose were mixed at a ratio of 1:3:4 by weight and carbonized at 800 °C for 5 h to create three different silicon-carbon composites.

Industrial waste silica preparation of silicon carbide ...

Silicon particles with uniform sizes were formed by cleaning solid organic wastes from the silicon industry with ether and nitric acid and ball milling the products. The resulting silicon was then used to prepare anode materials for lithium-ion batteries by mixing the silicon with graphite microspheres (GMs) and sintering the mixture in the presence of sucrose.

Silicon Carbide Formation Enhanced by In-Situ

2018-9-18  It is suggested that the thermal energy associated with the combustion of such off-gas can at least partially be stored in the form of chemical energy, by production of silicon carbide (SiC) from waste materials generated on-site. Saddow and Agarwal presented a general review of SiC associated production processes. Typically, SiC is commercially produced by Acheson- or Lely-type processes.
