Publication number: 20200067092Abstract: Method for producing a powder comprising particles (26) comprising amorphous, micro- or nano-crystalline Silicon nitride. The method comprises the steps of supplying a reactant gas (12) containing Silicon, and a reactant gas (12) containing Nitrogen, to a reaction chamber (16) of a reactor (10), and heating said reactant gases (12) to a temperature in the range of 510° C. to 1300° C. which is sufficient for thermal decomposition or reduction of the reactant gases (12) to take place inside the reaction chamber (16) to thereby produce a powder of amorphous, micro- or nano-crystalline particles (26) comprising Silicon nitride (SiNx) in which the atomic ratio of Silicon to Nitrogen is in the range 1:0.2 to 1:0.9. The produced powder of particles (26) may be used to produce a film, an electrode, such as an anode, for a battery, such as a Lithium ion battery.Type: ApplicationFiled: May 30, 2017Publication date: February 27, 2020Inventors: Martin Kirkengen, Asbjorn Ulvestad, Hanne F Andersen, Werner Filtvedt, Arve Holt, Hallgeir Klette, Trygve Mongstad, Jan Petter Maehlen, Ornulf Nordseth, Thomas Preston

Publication number: 20130089490Abstract: Method for producing nano- to micro-scale particles of a material by homogeneous thermal decomposition or reduction of a reactant gas (12) containing the material, whereby the method comprises the steps of supplying the reactant gas (12) to a reaction chamber (16) of a reactor via at least one inlet, and a) heating the reactant gas (12) to a temperature sufficient for thermal decomposition or reduction of the reactant gas (12) to take place inside the reaction chamber (16), or b) confining a temperature dependent reaction or reaction sequence involving a plurality of reactants inside the reaction chamber (16). The method comprises the step of supplying a primary gas (22) through a porous membrane (20) constituting at least part of at least one wall of the reaction chamber (16) to provide a protective inert gas boundary to minimize or prevent the deposition of the material on the porous membrane (20).Type: ApplicationFiled: October 11, 2012Publication date: April 11, 2013Inventors: Wener FILTVEDT, Arve Holt
