Abstract

The present invention relates to a preparation method of zinc oxide nano crystal and its equipment. Said equipment includes O2 flow meter, Ar flow meter, reaction furnace, heating furnace and metal zinc powder placed in its interior, reaction bin, small hole, microwave, K9 glass window, reaction furnace, vacuum pump, base bottom, base seat, adulterant metal plate and working table. Its preparation method includes the following steps: utilizing heat effect of microwave to heat adulterant to above vaporization temperature to produce high-temperature plasma, making said plasma be orientationally locally expanded and reacted with oxygen gas in the reaction furnace and metal zinc vapour moving along Ar gas flow so as to form several zinc oxide nano crystals of nano line, nano tower and nano granules which are completely identical in specific form and quality.

Description

Technical field: [0001] The invention belongs to the technical field of ceramic materials, relates to a method and device for preparing zinc oxide nanocrystals, and particularly refers to a method and device for preparing zinc oxide nanocrystals by microwave-induced dopant oxidation. Background technique: [0002] The common zinc oxide nanocrystal preparation technology is to use physical vapor deposition (PVD), chemical vapor deposition (CVD), pulsed laser deposition (PLD) and other methods to increase the temperature of the metal zinc powder to vaporize the zinc powder, and Gas O in the reaction tube (reactor) 2 The reaction occurs, and then returns to room temperature after holding for a period of time, and zinc oxide crystals are deposited on the substrate (such as silicon wafer). If some other metal ions are doped as additives or catalysts during the reaction, the resulting ZnO nanocrystals will have different shapes and properties, and will have a wider range of uses.
