Antimony(III) Oxide is the inorganic compound with the formula Sb2O3. Antimony Trioxide is an industrial chemical and also occurs naturally in the environment. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Antimony Trioxide is a chemical used in the manufacture of some polyethylene terephthalate (PET) plastic, which is used to make food and beverage containers. Antimony Trioxide is also added to some flame retardants to make them more effective in consumer products, including upholstered furniture, textiles, carpeting, plastics, and children’s products.

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.
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.
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.
Strontium Carbonate (SrCO3) is a water insoluble carbonate salt of strontium, that can easily be converted to other Strontium compounds, such as the oxide by heating (calcination).
Sodium Antimonate (NaSbO3) is a kind of inorganic salt, and also called sodium metaantimonate. White powder with granular and equiaxed crystals. High temperature resistance, still does not decompose at 1000 ℃. Insoluble in cold water, hydrolyzed in hot water to form colloid.
Sodium Pyroantimonate is an inorganic salt compound of antimony, which is produced from antimony products such as antimony oxide through alkali and hydrogen peroxide. There are granular crystal and equiaxed crystal. It has good chemical stability.
Strontium Nitrate appears as a white crystalline solid for uses compatible with nitrates and lower (acidic) pH. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards.
As a moderately water soluble crystalline antimony source, Antimony Triacetate is the compound of antimony with the chemical formula of Sb(CH3CO2)3. It is a white powder and moderately water-soluble. It is used as a catalyst in the production of polyesters.
Antimony Pentoxide (molecular formula: Sb2O5) is yellowish powder with cubic crystals, a chemical compound of antimony and oxygen. It always occurs in hydrated form, Sb2O5·nH2O. Antimony(V) Oxide or Antimony Pentoxide is a highly insoluble thermally stable Antimony source. It is used as a Flame retardant in clothing and suitable for glass, optic and ceramic applications.
Colloidal Antimony Pentoxide is made through a simple method based on reflux oxidization system. UrbanMines has detaily investigated about the effects of experimental parameters on the colloid stability and size distribution of the final products are carried out. We specialize in offering colloidal antimony pentoxide in a wide range of grades developed for specific applications. The particle size ranges from 0.01-0.03nm up to 5 nm for the sols.
Antimony Trisulfide is a black powder, which is a fuel used in various white star compositions of the potassium perchlorate-base. It is sometimes used in glitter compositions, fountain compositions and flash powder.
Antimony is a bluish-white brittle metal, which has low thermal and electrical conductivity. Antimony Ingots have high corrosion and oxidation resistance and are ideal for conducting various chemical processes.
Nickel Carbonate is a light green crystalline substance, which is a water insoluble Nickel source that can easily be converted to other Nickel compounds, such as the oxide by heating (calcination).
Nickel Chloride is an excellent water soluble crystalline Nickel source for uses compatible with chlorides. Nickel(II) chloride hexahydrate is a nickel salt that can be used as a catalyst. It is cost effective and can be used in a variety of industrial processes.
Nickel(II) Oxide is a light green solid and does not dissolve in water. Sometimes it is gray because all of the nickel is not in the +2 oxidation state. It is used to make alloys and other nickel compounds. It is also used in ceramics.
Niobium Oxide, sometimes called columbium oxide, at UrbanMines refer to Niobium Pentoxide (niobium(V) oxide), Nb2O5. Natural niobium oxide is sometimes known as niobia.
