  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 im

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: 1. 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 product

Ammonium Metatungstate in Thermal Insulating

Ammonium metatungstate (AMT) can be used as a thermal insulating material due to its unique thermal properties. When AMT is heated, it decomposes to form tungsten oxide, which has excellent thermal stability and a high melting point. This makes it an ideal material for use in high-temperature applications. AMT can be used as a thermal insulating material in a variety of forms, including coatings, fibers, and composites. For example, AMT can be applied as a coating on the surface of a substrate to provide thermal insulation. It can also be used as a filler material in polymer composites to improve their thermal properties. One advantage of using AMT as a thermal insulating material is its low thermal conductivity. AMT has a thermal conductivity of around 0.06 W/m·K, which is much lower than most metals and other common insulating materials. This means that AMT can provide excellent thermal insulation while also being lightweight and easy to handle. Overall, AMT ca

Ammonium metatungstate (AMT) is a white crystalline powder that is used as a precursor to make tungsten metal and tungsten alloys, as well as a catalyst and a pigment in various industrial applications. AMT is generally considered to be relatively low in toxicity and not a significant environmental hazard, as long as it is handled and disposed of properly. However, as with any chemical, prolonged or excessive exposure can potentially be harmful. In terms of human health, ingestion or inhalation of AMT can cause irritation of the respiratory tract, eyes, and skin. It may also cause gastrointestinal distress, such as nausea, vomiting, and diarrhea. However, the risk of exposure to AMT is generally considered to be low, as it is not commonly found in consumer products or in the environment. In terms of environmental hazards, AMT is not considered to be toxic to aquatic life, but it may have harmful effects on soil microorganisms and plant growth if it is released

  Ammonium metatungstate (AMT) is a white crystalline powder that is used in the production of tungsten metal, tungsten carbide, and other tungsten compounds. It is a stable compound under normal conditions, but it can decompose at high temperatures or in contact with strong acids or oxidizing agents. Here are some guidelines for the safe storage and handling of ammonium metatungstate: Storage: AMT should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, oxidizing agents, and combustible materials. The storage area should be clearly labeled and access should be restricted to authorized personnel only. Handling: When handling AMT, wear appropriate personal protective equipment such as gloves, goggles, and a lab coat. Avoid direct contact with skin, eyes, and clothing. AMT should be handled in a fume hood to prevent inhalation of the powder. Use a dust mask or respirator if necessary. Transportation: AMT sho
