Ammonium paratungstate (APT) - An intermediate raw material with excellent reducibility and processability! A high-purity material ideal for hard tools, electronic materials, catalysts, and phosphors!
■What is Ammonium Paratungstate (APT)■ Ammonium paratungstate (APT) is a white to light yellow crystalline powder that serves as an intermediate raw material used in the refining and processing of tungsten. Its chemical formula is (NH₄)₁₀[H₂W₁₂O₄₂]·xH₂O, and it is utilized in various applications as an inorganic compound with high purity and stability. ■Key Points of the Proposal■ APT is an important material that serves as a precursor for tungsten powder and tungsten oxide (WO₃), forming the basis for various tungsten products. - Hard Metal Tools: Tungsten powder obtained by reducing APT is used in hard alloy materials for drills and molds. - Electronic Materials: Suitable for applications requiring high-temperature resistance, such as electrodes and heater components. - Phosphors and Catalysts: Also utilized as a raw material for tungsten oxide-based phosphors and denitration catalysts. Additionally, due to its water solubility and uniform particle characteristics, it is suitable for slurry preparation and precision processing. ⇒ High-purity and highly reliable APT meets a wide range of needs from material development to mass production processes.
