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 shielding plate is used to absorb X-rays scattered and transmitted by a CT scanner. You know, some X-rays could enter the surrounding environment through scattering and transmission during CT scanning, which may affect the health of operators, patients and their accompanying family members.

Tungsten alloy radiation shield is an essential protection part on CT machine. The radiation shield made of high density tungsten-based alloys may be a tungsten alloy plate, a tungsten alloy tube or a tungsten alloy shielding device. You know, CT examination is X-ray examination, which produces ionizing radiation. In order to minimize the radiation to the patient, a tungsten alloy shield with excellent X-ray absorption shielding effect is necessary.

Tungsten alloy PET unit dose pig is innovative and cost effective to help improve the safety and efficiency of radiopharmaceutical handling procedures. You know, radiographic imaging has become an integral part of the diagnosis and management of patients. To do PET (Positron Emission Computed Tomography) examination, PET imaging agent is needed to make the imaging clearer. At present, the most commonly used PET imaging agent in clinic is 18F-FDG imaging (γ-ray).

Tungsten alloy syringe pig is a tungsten alloy shield made of high quality tungsten-based alloy, which is specially designed and manufactured by a special process, to fit in to single dose holder for normal lab operations or clinical diagnosis or treatment. Tungsten alloy syringe pig has high density of up to 18.89 g/cm3, so that it has excellent radiation shielding performance (both X-ray and gamma radiation absorption), and therefore it is mainly used to protect medical personnel from being irradiated by the injection liquid during injection, transfer and experiment.

Medical tungsten alloy radiation protection box refers to a type of protective container made of high-quality tungsten based alloy for storage and transportation of medical radioactive sources, which has more excellent X-ray absorption performance and gamma ray absorption performance than a lead box. More importantly, medical tungsten alloy radiation protection box is non-toxic and non-polluting, while lead is a toxic heavy metal.

Tungsten alloy radiation shielding syringe is a type of syringe protective sleeve that can be used to shield radiation sources such as X-rays and γ-rays. It means that tungsten alloy syringe protective sleeve is an indispensable shield in the field of nuclear medicine. This kind of syringe protective sleeve is mainly made of tungsten-based alloy, which has the characteristics of strong radiation shielding performance, environmental protection, non-toxic, anti-drop, chemical resistance, etc.

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.

Tungsten alloy radiation shielding is an excellent way to protect doctors, nurses, patients and their family members against radiation. It means that tungsten alloy can shield radiation. You know, there are three main methods of radiation protection. They are time protection, distance protection and shielding protection. Wherein, the main point of shielding protection is to place a shielding material that can effectively absorb radiation between the radiation source and the human body.

Tungsten carbide milling tool, also called tungsten carbide milling cutter, is a cutting tool typically used in milling machines or machining centers to perform milling operations. It removes material by its movement within the machine or directly from the cutter's shape. It is mainly used for machining planes, steps, grooves and forming surfaces on PCB boards, bakelite boards, plastics, wood, etc. Well, do you know why tungsten carbide milling tool breaks?
