Nano-scale fabrication of nitride particles while there are already a number of relevant reports, but the international community still does not have a systematic, comprehensive method of thermal plasma (NPMR) study on preparation of nitride nanoparticles.
Nano-particles or nano-powder, usually refers to the particle size 100nm, is a cross between atoms, molecules and macroscopic objects in the intermediate state between solid materials. Its unique physical and chemical properties make it popular, is expected to have wide application in high density magnetic recording materials absorbing material; magnetic fluid materials radiation materials monocrystalline silicon and polishing materials for precision optical components; electrode materials for advanced batteries and solar cell materials efficient catalyst efficient combustion-supporting agent sensors; ceramics with high toughness; human restoration materials; anticancer agent and so on.
Nano particles material of preparation method variety, currently compared mature of method main is divided into three big class: < a > gas phase method: has gas in the evaporation method, such as resistance heating method, and HF induction heating method, and plasma heating method, and electron beam heating method, and laser heating method,; chemical gas instead should method, such as laser induced chemical its instead should method, and plasma strengthened chemical its instead should method,; chemical gas phase condensed method; sputtering method etc. < Ii > liquid phase, such as precipitation, hydrolysis, aerosol, emulsion method and-melt Adhesive gel. Three solid method: pyrolysis, solid phase reaction method, for example by ball-milling method.
Had has many people using similar of method preparation nitride real, but they more using elemental and ammonia, containing nitrogen of compounds, used hot, stereo heating chemical reactions of approach for preparation: but currently also rarely was using hot plasma method will nitrogen directly and pure of elemental reaction preparation nitride real particles, especially also no preparation nitride silicon, and nitride boron, and nitride gallium of system research of reported.
