Abstract
Method for producing a powder comprising particles () comprising amorphous, micro- or nano-crystalline Silicon nitride. The method comprises the steps of supplying a reactant gas () containing Silicon, and a reactant gas () containing Nitrogen, to a reaction chamber () of a reactor (), and heating said reactant gases () to a temperature in the range of 510° C. to 1300° C. which is sufficient for thermal decomposition or reduction of the reactant gases () to take place inside the reaction chamber () to thereby produce a powder of amorphous, micro- or nano-crystalline particles () 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 () may be used to produce a film, an electrode, such as an anode, for a battery, such as a Lithium ion battery.
