Abstract

The invention provides a manufacturing apparatus for nanometer powder, The apparatus contains: a reaction room with an incidence window; an laser generator used to generate laser; an optical system, which is located on the incidence window and used to focus the laser generated by the laser generator, and then the focused laser enters the reaction room through the incidence window; at least one input device of reaction air providing air for the reaction room; a vacuumizing device used to vacuumize the reaction room; a powder collecting unit to collect the powder produced by reaction of air; and a microwave generator used to generate the microwave which causes the cyclotron resonance of the microwave electron. The invention also provides a manufacturing method for nanometer powder.

Description

【Technical field】 [0001] The invention relates to a nano powder preparation device and a preparation method. 【Background technique】 [0002] Nanomaterials refer to granular materials with a size ranging from 1 to 100 nanometers (nm) and macroscopic materials with a size ranging from 1 to 100 nm. Due to the characteristics of small size effect, quantum effect, surface effect, and macroscopic quantum tunneling effect, nanomaterials have advantages that ordinary materials cannot match, such as low melting point, low density, high strength and good toughness. And high temperature oxidation resistance, corrosion resistance and good dielectric properties, acoustic properties, optical stability, etc. Nanomaterials have been widely used in catalysts, high polymer latex, cement, ceramics, carbon fiber materials, medicine, and optoelectronic or microelectronic devices. [0003] The development and application of nanomaterials have attracted more and more attention, and the preparati...
