  • Patent number: 7964172
    Abstract: A method for synthesis of high surface-area (>100 m2/g) and nanosized (?100 nm) silicon powder by initiation of self-sustained combustion reaction in a mixture of silicon dioxide and magnesium powders in a sealed reactor chamber under pressurized inert gas atmosphere. A specific feature of the method is rapid cooling of the product at a rate of 100 K/s to 400 K/s in the area directly behind the combustion front.
    Type: Grant
    Filed: October 13, 2009
    Date of Patent: June 21, 2011
    Inventors: Alexander Mukasyan, Vasiliy Mukasyan, Mikael Nersesyan
  • Patent number: 7939044
    Abstract: A method of manufacturing a silicon carbide powder with submicron size of powder particles wherein a homogeneous reactant mixture comprising a source of silicone, a source of carbon, and polytetrafluoroethylene is locally preheated in a sealed reaction chamber filled with an inert gas under pressure of 20 atm to 30 atm to a temperature sufficient to initiate an exothermic self-propagating reaction ranges from 650K to 900K. In the aforementioned homogeneous reactant mixture, the carbon source is used in the amount from 63 wt % to 68%, the silicon source is used in the amount of from 20 wt. % to 25 wt. %%, and the activated additive is used in the amount of from 8 wt. % to 15 wt. % per 100% of the entire homogeneous reactant mixture.
