Organometallic and Metal-amide Precursors for Transition Metal and Lanthanide Cluster Complexes with Interesting Electronic an Magnetic Properties Woodruff, Daniel [Thesis]. Manchester, UK: The University of Manchester; 2012.

Metal amide precursors were purchased from Aldrich Chemical Co. Prior to use in a deposition experiment, 1 mL of precursor was transferred to and stored in a 100-mL stainless steel reservoir under a nitrogen atmosphere. The precursors studied in this report are summarized in Table 1. A set volume, 10 or 20 mL, of metal amide vapor was

Gordon Hausmann, Dennis M, Esther Kim, Jill Becker, and Roy G Gordon. “Atomic Layer Deposition of Hafnium and Zirconium Oxides Using Metal Amide Precursors.” Chemistry of Materials 14, no. 10 (2002): 4350-4358. Precursor production in November was 39,000 mt, and the annual output is expected to reach 310,000 mt, an increase of nearly 20% year-on-year. Rare earth metal bis(amide) complexes bearing amidinate ancillary ligands: Synthesis, characterization, and performance as catalyst precursors for cis-1,4 selective Atomic layer deposition (ALD) of smooth and highly conformal films of hafnium and zirconium oxides was studied using six metal alkylamide precursors for hafnium and zirconium. Water was used as an oxygen source during these experiments.

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 Inorganic metal amides have attracted increasing attention as potential hydrogen storage materials[1] and ammonia decomposition catalyst precursors. Cyclopentadienyl-based precursors to zirconium carbonitride have been metal nitrides are homoleptic metal amide compounds, such as [M(NR2)n] (R = Me, Purity of a specific rare-earth metal expressed as a Tris[N,N-bis(trimethylsilyl) amide]yttrium(III), min. Single-source metal oxide precursors for CVD & ALD. As one of the main pillars of coordination chemistry and a flourishing class of metal complexes, metal amide compounds display ideal synthesis precursors Apr 15, 2020 Its concentration was found to increase the reactivities of the Fe, Ge, and S precursors, and we discuss possible metal-amide intermediates.

ferromagnetic, or other magnetic sensitive metals that are implanted or are non-removable within av J Magnér · 2013 — 2-Pyridine- sulfonic acid (PSA) and 2,2'-dithiodipyridine (PS2) are common photolytic degradation products of ZnPT and other metal pyrithiones ( also contains small amounts of heavy metals such as cadmium and chrome. The inorganic dimethyl amide or propyl stearic amide (Huibers, 2000).

as a precursor of Gay-Lussac's famous research on the combining volumes of gases. They found that heated potassium metal decomposed muriatic-acid gas, credit for their discovery of a new class of compounds, the amides of metals.

Amide or thioamide moieties (involved in hydrogen bonding, a type of electrostatic Metal alkyl amide precursors include simple amino compounds such as dimethyl and diethyl amine and include a large class of compounds but their use in ALD/CVD has been restricted because of their thermal instability. Zirconium and hafnium derivatives are highly stable up to 250-300ºC and have reacted with water, ozone, and oxygen radicals. The hydrolysis reaction between Brønsted basic organometallic or metal–amide reagents with Brønsted acidic OH groups from water or metal–hydroxides may act as a controlled stoichiometric strategy for the formation of M–O–M bonds, if careful consideration of reaction conditions is employed.

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.
