And Flow Of The Nano-zno Prepared By Precipitation Process Research

Compared with nanometer ZnO and commom ZnO, nanometer ZnO has more special capability ,such as piezoelectricity, fluorescence, no-transplant, and the capability of absorb and scatter ultraviolet radiation, nanometer ZnO is used to the material that piezoelectricity resistance, piezoelectricity material, gas sensor, recording image material, catalyzer etc. Therefore , more studies are focused on the theory analysis and application of the nanometer ZnO.We had gone deep into study and successly prepared nanometer-size ZnO based on paralled flow precipitation method with Zincdross. We analysis and compare the abuse of some kinds of liquid phase method of producing nanometer-size ZnO and then make certain the craftwork. We confirm the furthest condition on the base of paralled flow precipitation method. At the same time, we prepared nanometer ZnO by adoption the technology of ultrasonic, microwave and surface-coated. Nanometer ZnO is high disperse, low reunite, high alive and single by above method. Product's pure is high by XRD analyzed. Product is sphericity and size about 40nm by SEM and TEM inspected. The decompose temperature of precursor is 400C TG analyzed. The nanoparticles surface-coated with dispersant by IR analyzed.Prepared nanometer-size ZnO based on paralled flow precipitation method with Zincdross. In this progress we used the technology of ultrasonic, microwave and surface-coated. Granularity is thin, distributing is narrow, disperssing is fine. Especially the technics need not highness equipment and may easily industrialization.The study of prepared nanometer-size ZnO not only open up new product but also find out a new way of utilizeation of Zincdross. Especially, this progress has high stratagem in using resource of zinc , advance level of utilize and protecting circumstance...
