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.
Yttrium(yttrium oxide,Y2O3)stabilized zirconia(zirconium dioxide,ZrO2)grinding media have high density, super hardnes and excellent fracture toughness, enabling to achieve superior grinding efficiencies compared to other conventioanl lower density media.UrbanMines specializes in producing Yttrium Stabilized Zirconia (YSZ) Grinding Beads Media with the highest possible density and smallest possible average grain sizes for use in semiconductor, grinding media, etc.
CZC (Ceria Stabilized Zirconia Bead) is a high density zirconia bead that is suitable for large capacity vertical mills for dispersion of CaCO3. It has been applied to the grinding CaCO3 for high viscosity paper coating. It is also suitable for the production of high-viscosity paints and inks.
Zirconium Silicate – Grinding Media for your Bead Mill. Grinding Beads for Better Grinding and Better Performance.
Zirconium(IV) Chloride, also known as Zirconium Tetrachloride, is an excellent water soluble crystalline Zirconium source for uses compatible with chlorides. It is an inorganic compound and a white lustrous crystalline solid. It has a role as a catalyst. It is a zirconium coordination entity and an inorganic chloride.
Cesium Nitrate is a highly water soluble crystalline Cesium source for uses compatible with nitrates and lower (acidic) pH.
High purity (over 98.5%) Beryllium Metal Beads are in small density, large rigidity and high thermal capacity, which has excellent performance in the process.
99% Beryllium Oxide is a white colored, crystalline, inorganic compound that emits toxic fumes of beryllium oxides upon heating.
Beryllium Fluoride is a highly water-soluble Beryllium source for use in oxygen-sensitive applications.UrbanMines Materials produces to nuclear purity standard grade.
Barium Carbonate is manufactured from natural barium sulfate (barite). Barium Carbonate standard powder, fine powder, coarse powder and granular are all can be custom-made at UrbanMines.
Barium hydroxide, a chemical compound with the chemical formula Ba(OH)2, is white solid substance, soluble in water, the solution is called barite water, strong alkaline. Barium Hydroxide has another name, namely: caustic barite, barium hydrate. The monohydrate (x = 1), known as baryta or baryta-water, is one of the principal compounds of barium. This white granular monohydrate is the usual commercial form. Barium Hydroxide Octahydrate, as a highly water insoluble crystalline Barium source, is an inorganic chemical compound that is one of the most dangerous chemicals used in the laboratory. Ba(OH)2.8H2O is a colorless crystal at room temperature. It has a density of 2.18g / cm3, water soluble and acid, toxic, can cause damage to the nervous system and digestive system. Ba(OH)2.8H2O is corrosive, may cause burns to eye and skin. It may cause digestive tract irratation if swallowed. Example Reactions: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3
Bismuth is a silvery-red, brittle metal that is commonly found in the medical, cosmetic, and defense industries. UrbanMines takes full advantage of High Purity (over 4N) Bismuth Metal Ingot's intelligence.
Bismuth Trioxide (Bi2O3) is the prevalent commercial oxide of bismuth. As a precursor to the preparation of other compounds of bismuth, bismuth trioxide has specialized uses in optical glass, flame-retardant paper, and, increasingly, in glaze formulations where it substitutes for lead oxides.
Bismuth(III) Nitrate is a salt composed of bismuth in its cationic +3 oxidation state and nitrate anions, which the most common solid form is the pentahydrate. It is used in the synthesis of other bismuth compounds.
UrbanMines specializes in producing high purity Cobalt Powder with the smallest possible average grain sizes, which are useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Our standard powder particle sizes average in the range of ≤2.5μm, and ≤0.5μm.
Cobalt (II) Oxide appears as olive-green to red crystals, or greyish or black powder. Cobalt (II) Oxide is used extensively in the ceramics industry as an additive to create blue colored glazes and enamels as well as in the chemical industry for producing cobalt(II) salts.
Cobaltous Chloride (CoCl2∙6H2O in commercial form), a pink solid that changes to blue as it dehydrates, is utilized in catalyst preparation and as an indicator of humidity.
