Thoriated tungsten needle is a tungsten needle containing thorium element. A certain amount of thorium element is added during its manufacturing process to enhance its mechanical properties and corrosion resistance. Thorium tungsten needles have high strength and hardness, as well as good corrosion resistance and high temperature performance, so they are widely used in many fields.
Thorium is a radioactive element, so thorium-tungsten needles have certain radioactive contamination. When using thoriated tungsten needles, you need to pay attention to safety issues, such as wearing professional protective equipment and avoiding prolonged or high-intensity contact. In addition, due to the strong chemical activity of thorium element, thorium tungsten needles are easy to volatilize at high temperatures, so care needs to be taken to prevent inhalation and contact.
When manufacturing thoriated tungsten needles, their high strength and hardness properties are usually achieved by adding thorium element to the tungsten matrix. This addition process can be achieved through powder metallurgy, electroplating, spraying and other methods. During the manufacturing process, it is also necessary to pay attention to controlling parameters such as temperature and pressure to ensure that the shape and size of the thoriated tungsten needle meet the requirements and to avoid cracks and other defects.
The application fields of thoriated tungsten needles mainly include chemical industry, aerospace, electronic manufacturing and other fields. In these fields, thoriated tungsten needles are widely used due to their high strength, high hardness, corrosion resistance and high temperature performance. For example, in the chemical industry, thoriated tungsten needles can be used as reactor support materials or catalyst carriers; in the aerospace field, thoriated tungsten needles can be used as heating elements in high-temperature furnaces, etc.
In short, a thoriated tungsten needle is a tungsten needle containing thorium element, which has the characteristics of high strength and high hardness. It is mainly used in fields that require high strength and corrosion resistance. You need to pay attention to safety issues when using it and choose appropriate protective measures.
