Thermal Decomposition Behaviors of Ammonium Paratungstate (APT) in Hydrogen

Image of APT

Ammonium paratungstate (APT) is regarded as an important precursor of many tungstic product. A major product from thermal decomposition of APT is tungsten trioxide (Wo3), which is the active phase in tungsten-based catalysts. Furthermore, it is applied in varied field of gas sensors, catalysis, electrochemistry, and photocatalysis owing to its excellent gasochromic, acidity, electrochromic and photochromic properties. Meanwhile, tungsten trioxide, with a band gap between 2.4 and 2.8 eV, is a visible light response catalyst with stability under acidic conditions, which makes it a suitable choice for the photocatalytic oxidation of organic pollutants under solar irradiation.

Tungsten Alloy Syringe Protective Box

tungsten alloy syringe protective box picture

Tungsten alloy syringe protective box is a tungsten alloy box specially designed for storing and transporting syringes containing radioactive liquid. As tungsten alloy has excellent radiation shielding performance and its shielding effect is better than traditional shielding material lead, the volume of tungsten alloy shield is much smaller than that of lead shield, which can save storage space and facilitate transportation. In addition, tungsten alloy is an environmentally friendly shielding material, while lead is toxic.
