Spherical  Zinc Oxide ZNO Nanostructures Application     Compared with ordinary zinc oxide, Zinc Oxide ZNO Nanostructures has many other excellent performance. At present the main application areas are rubber products, high-grade paint, ink and paint, sunscreen and anti-ultraviolet fabric, sewage treatment,etc.   1. Zinc Oxide ZNO Nanostructures in Rubber Industry   ZnO nanopowder is the most effective inorganic active agent and vulcanization accelerator in rubber industry.  Zinc Oxide ZNO Nanostructures with small particle size 20-30nm, larege specific surface area, good dispersion, loose, porous, good liquidity and good affinity with rubber, easily dispersed whilc melting, low heat plastic material, breaking small deformation , good elasticity, can improve the material process performance and physical properties, thus it's used in the manufacture of high-speed wear-resistant rubber products, such as aircraft tires, high-class passenger car radial tire, with performance of anti-aging, anti-friction fire, long life, and greatly improves finish, mechanical strength, temperature and aging resistance of rubber products,especially wear resistance.  In addition, Zinc Oxide nano as a vulcanization system in the rubber system, whose additive is high.The large specific gravity and  filling amount of ordinary ZnO, whose influence on its material density, product life and energy consumption is detrimental. However, the use of Nano grade Zinc Oxide, the amountis only 30% -50% compared to the ordinary one,which reduces the cost of production, and the performance in the tensile properties, heat, aging, etc are far superior to ordinary zinc oxide powder.   2. Zinc Oxide ZNO Nanostructures in Ceramic industry   Because of very small particle size, large specific surface area and high chemical properties,nano ZnO can significantly lower the sintering densification of materials, save energy, make the ceramic material composition densification, homogenization, improve the performance of ceramic materials, the reliability of its use. Controling the composition and structure of materials on the structural level of nano materials is conducive to give full potential performance of ceramic materials. In addition, because the particle size of ceramic material determines the microstructure and macroscopic properties of ceramic materials, if the particles of the powders are uniformly packed and the sintering shrinkage is uniform and the grain grows uniformly, then the smaller the particle size, the smaller the resulting defects, and the higher the strength of the prepared material, which may result in some unique performance that large particles do not have.   3. Nano Zinc Oxide in Other Areas With the deepening understanding of the performance of nano Zinc Oxide, its applications continue to expand, for example, in the traditional coating technology, adding nano ZnO can further improve the protective capacity, making resistance to atmospheric damage and anti-degradation, color,etc.With a certain percentage of Zinc Oxide nanopowder added to the propionic acid coating, it can be made into excellent nano antibacterial coating. Making use of the sensitive properties of nano ZnO, can produce a high sensitivity gas alarm and hygrometer.           As a new type of semiconductor materials, Zinc Oxide ZNO Nanostructures has become a new type of high-performance fine inorganic products in the 21st century. At present, researchers at home and abroad have developed a variety of methods to prepare various forms of nano zinc oxide products and achieve a lot. However, there are still some shortcomings such as high cost, complicated process and difficulty of industrialization in the preparation method. In addition, the research on the structure and application performance of nano ZnO is not deep, so the follow-up research will focus on the development of simple, high-efficient and easy industrial production methods. With the further study of the material structure on its optical, electrical, magnetic and acoustic properties, it is expected that with the continuous improvement of the preparation method of nano zinc oxide, the nano-size effect of nano-sized oxides, and the study will have a full-speed development stage. by Jemma

       Nano ITO indium tin powder is a new kind of high-functional inorganic material with a size of 1-100nm which is oriented to the 21st century. Because of miniaturization of crystal grains,its surface electronic structure and crystal structure change, resulting in a surface effect, volume effect, quantum size effect and the macro-tunnel effect and high transparency, high dispersion and so on that a macroscopic object does not have. In the aspects of photoelectric sensitivity, nano ITO has the special properties and new uses that the ordinary indium tin oxide can not match, such as used as stealth materials, solar collector materials and collectors ect.         Nano ITO indium tin oxide powder is an excellent semiconducting material that with outstanding properties, which is widely used in conductive shell, gas sensor, photodetector, liquid crystal display and so on. In recent years, nano powder preparation technology continues to develop and improve, but the nanopowder has a high active surface, the surface hanging a lot of free radicals, so when adding some other matrix materials in nano powder, it is easily to lead to the formation of large particles of nano particles agglomeration, which play a significant impact on the properties’ performance of optical, electrical, magnetic and other aspects. Therefore, it is very important to disperse the powders well before using, which can help the ITO particles achieve the best properties.         Taken the ITO powder as raw material, through a certain process to prepare ITO powders into a ITO rods, also known as ITO target (ITO ceramic target). With the ITO target, it can be further to manufacture TIO transparent conductive film glass. The main component of ITO film is indium tin oxide. In the case of a thickness of only a few thousand angstroms, indium oxide is with high transmittance and tin oxide has conductive ability. Liquid crystal display used in ITO glass is a high transmittance of conductive glass. by Jemma
