In this research, Tungsten oxide nanoparticles were synthesized by sol-gel method. Using sol-gel method, nanoparticles can be produced with the same sizes. Raw materials of this method are hydrated salt or metal chloride, which are cheap and abundant. In this study, materials which were used are as follows: Tungsten di-chloride di-oxide (WO 2 Cl 2 ), Ethanol with high purity, Cyclo-hexane, distilled water and Trimethyloxetane (TMO) as a gelation factor. After producing gel, It was washed for 3 days by pure Ethanol. Subsequently, the gel was washed again for 2 days by Cyclo-hexane. Thereafter, produced gels was dried for 3 days in vacuum oven at temperature of 210 °C and pressure of 10 mbar. The produced powders scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Thermo Gravimeter Analysis (TGA) and XRD had been done on. Subsequently, their results showed that crystallized particles WO 3 are present in the form of ? or ? and most commonly are in the form of ?-wo3, also almost peaks in XRD patterns are related to Tungsten oxide. Nanoxide purity was determined 94% according to Thermo Gravimetry Analysis (TGA). Synthesized particles at temperature of 210 °C formed in shape of square and angularity that it is determined by Scanning Electron Microscope (SEM) test. After synthesis of Tangusten nanoxide, energizing nanocomposite (Thermite) was synthesized. Energizing materials are substances, which store chemical energy in a fixed volume. Examples of the energizing materials are explosive flammable materials. The reaction is started by mechanical or thermal stimulation. In addition, the energy is released as heat. Thermite materials including fuel and oxidizer are mixed together. In this research, oxide nanoparticles were synthesized by sol-gel method using aluminum nanoparticles with a particle size of about 30 nm by mixing in a ultrasound devices in cyclo-hexane for 3 min. With this oxidizer, (Tungsten nanoxide) three modes including; stoichiometric, quantitative fuel-rich and fuel-rich prepared and then were characterized. Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Thermo Geravimetery Analysis (TGA), DTA and XRD tests were done for distribution pattern of particles, morphology, size of particles, reaction temperature and final products, respectively. SEM test results showed that the synthesized particles were in the nanometer scale and had high integrity. Scanning TEM test, which take photo from inside of samples, is determined the measure size of synthesized particle, which synthesized at 210 ?, to be lover with 100 nm and shape of them formed cubic and angularity. Reaction temperature of anoparticle Aluminum and Tungste nanoxide is determined to be 550-600 °C by heating analysis test (DTA) and main products of reaction were determined Tungsten and Aluminum oxide. .
