Raquel Garcia Volatile Liquid Precursors for the Chemical Vapor Deposition (CVD) of Thin Films Containing Alkali Metals - Volume 606 - Randy N. R. Broomhall-Dillard, Roy G. Gordon, Valerie A. Wagner Described are methods for deposition of metal-aluminum films using metal amidinate precursors and aluminum precursors. Such metal-aluminum films can include metal aluminum carbide, metal aluminum nitride and metal aluminum carbonitride films.

China’s Gansu province is mulling a plan to encourage local companies to stockpile up to 436,000 mt of nonferrous metals for at least seven months to support the market which has been hit by the COVID-19 pandemic crisis. Compounds, and oligomers of the compounds, are synthesized with cyclic amine ligands attached to a metal atom. These compounds are useful for the synthesis of materials containing metals. Examples include pure metals, metal alloys, metal oxides, metal nitrides, metal phosphides, metal sulfides, metal selenides, metal tellurides, metal borides, metal carbides, metal silicides and metal germanides.

2 dagar sedan · Silicon metal prices moved steadily in early March but trended lower in the last ten days of the month as stocks piled up at some silicon plants as trades weakened. Large output in Xinjiang and slower procurements from downstream aluminium alloy plants weighed on prices of silicon metal 553# with

Group 2 complexes[edit] Since several years metal-organic compounds are widely used as molecular precursors for the chemical vapor deposition process (MOCVD). The success of this method is mainly due to its adaptability and to the increasing interest for the low temperature deposition processes. : A mixture of the pre-synthesized metal amide precursor and nanocrystalline silicon (Alfa Aesar, average grain size 50 nm); silicon powder (Cerac, 99.999 %) or silicon diimide (synthesized according to the literature) 29 was ground and transferred into a tungsten crucible under an argon atmosphere inside a glovebox.
