Abstract: Disclosed are nickel allyl amidinate precursors having the formula: wherein each of R1, R2, R3, R4, R5, R6, R7, and R8 are independently selected from H; a C1-C4 linear, branched, or cyclic alkyl group, a C1-C4 linear, branched, or cyclic alkylsilyl group (mono, bis, or tris alkyl); a C1-C4 linear, branched, or cyclic alkylamino group; or a C1-C4 linear, branched, or cyclic fluoroalkyl group. Also disclosed are methods of synthesizing and using the disclosed precursors to deposit nickel-containing films on one or more substrates via a vapor deposition process.

Abstract: Process for melting a furnace charge, with post-combustion of the smokes by njecting an oxygenated gas in the furnace atmosphere as a series of jets flowing according to a tangential component in the space between electrodes and cylindrical furnace partition of the furnace, in a direction of injection so as to produce a rotary gas current about the vertical axis of the furnace and preferably in at least two series as two stepped levels to produce gas currents which rotate in opposite directions. Applications to electrical furnaces for the production of steel or ferro-alloys.
