B4C nanopowder has high thermal conductive, widely used in semiconductor components.

       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
