  What is Nano Yellow Tungsten Oxide? Yellow tungsten oxide (WO3, Nano Yellow Tungsten Oxide) is an oxide of tungsten with a yellow powder appearance. Two different particles of yellow tungsten oxide are different in size and show different colors. When the crystal size is about 1.5um, it appears yellow; when the crystal size is about 15um, it appears green. Although the appearance is different, the characteristics are similar. Physical Properties Of Nano Yellow Tungsten Oxide: Physical properties: yellow or bright green, finely divided yellow crystal powder, loose specific gravity 2.3~2.8g/cm3. Appearance and characteristics: yellow powder, stable at room temperature, the product passes through 80 mesh screen. Nano Yellow Tungsten Oxide Application: As an important intermediate in tungsten metallurgy industry, yellow tungsten oxide is widely used in metal tungsten powder and tungsten carbide powder, and then used in the production of metal tungsten products. Part of...

  What is Nano Tungstic Acid? Nano tungstic acid usually refers to nano yellow tungstic acid, an amorphous yellow powder. The properties of tungstic acid in water and acidic solutions are relatively stable, almost insoluble in water, soluble in alkali, slightly soluble in acid, but can react with water. And exist in a certain colloidal form. When tungstic acid is heated to 100°C, it loses a molecule of water and turns into tungsten trioxide. It is almost insoluble in acid, slightly soluble in hot water, and exhibits stable properties at temperatures below 150°C; In strong alkaline solutions, ammonia and hydrofluoric acid. Chemical formula of nano tungstic acid: H2WO4 or WO3·H2O Physical Properties Of Nano Tungstic Acid: Appearance color: light orange-yellow powder, insoluble in water. Purity: ≥99.9% Average particle size: 30~50nm Melting point: 1473℃ Nano Tungstic Acid Application: Due to its unique properties, tungstic acid was used as the most important and high...

    What Is Purple Tungsten Oxide? Purple tungsten oxide (WO2.72 or W18O49, Purple Tungsten Oxide or Violet Tungsten Oxide, VTO for short) is a kind of tungsten oxide, which is a purple finely divided crystal powder with a molecular weight of 227.36. Physical And Chemical Properties Of Purple Tungsten Oxide: Appearance: purple or blue-purple broken crystal powder Solubility: Insoluble in water, alcohol and most acids, soluble in ammonia and lye. Preparation method of purple tungsten oxide: The preparation of violet tungsten oxide is usually produced by controlling certain reducing conditions using ammonium paratungstate (APT), tungstic acid or tungsten trioxide (WO3) as raw materials. The preparation methods of violet tungsten usually include APT wet hydrogen direct reduction method, hydrogen tungstate reduction method, and APT mild reduction method. Uses of purple tungsten oxide: Preparation of tungsten powder, especially the preparation of nanometer, submicro...
