Tungsten Rod is pressed and sintered from our high purity tungsten powders. Our pure tugnsten rod has 99.96% tungsten purity and 19.3g/cm3 typical density. We offer tungsten rods with diameters ranging from 1.0mm to 6.4mm or more. Hot isostatic pressing ensures our tungsten rods obtain a high density and fine grain size. Tungsten Powder is mainly produced by the hydrogen reduction of high-purity tungsten oxides. UrbanMines is capable of supplying tungsten powder with many different grain sizes. Tungsten powder has often been pressed into bars, sintered and forged into thin rods and used to create bulb filaments. Tungsten powder is also used in electrical contacts, airbag deployment systems and as the primary material used to produce tungsten wire. The powder is also used in other automotive and aerospace applications.
Tungsten(VI) Oxide, also known as tungsten trioxide or tungstic anhydride, is a chemical compound containing oxygen and the transition metal tungsten. It is soluble in hot alkali solutions. Insoluble in water and acids. Slightly soluble in hydrofluoric acid.
Tungsten Carbide is an important member of the class of inorganic compounds of carbon. It is used alone or with 6 to 20 percent of other metals to impart hardness to cast iron, cutting edges of saws and drills, and penetrating cores of armour-piercing projectiles.
Cesium Tungsten Bronzes(Cs0.32WO3) is a near-infrared absorbing nano material with uniform particles and good dispersion. Cs0.32WO3 has excellent near-infrared shielding performance and high visible light transmittance. It has strong absorption in the near-infrared region (wavelength 800-1200nm) and high transmittance in the visible light region (wavelength 380-780nm). We have the successful synthesis of highly crystalline and high purity Cs0.32WO3 nanoparticles through a spray pyrolysis route. Using sodium tungstate and cesium carbonate as raw materials, cesium tungsten bronze (CsxWO3) powders were synthesized by low temperature hydrothermal reaction with citric acid as the reducing agent.
