Products Description
Tungsten Carbide Powder (WC powder for short) is a powdered compound composed of tungsten and carbon. It is dark gray powder with a black hexagonal crystal structure and metallic luster. Tungsten carbide powder is a good conductor of electricity and heat. Its hardness is similar to that of diamond. Tungsten carbide powder is insoluble in water, hydrochloric acid and sulfuric acid, but easily soluble in a mixture of nitric acid and hydrofluoric acid. When heated to about 500°C in air, it will be oxidized to become tungsten oxide.
There are many methods for preparing tungsten carbide powder. For example, the carbon thermal reduction method is to mix tungsten powder and carbon powder and react them at high temperature to obtain tungsten carbide powder. This method is one of the main methods for industrial production of tungsten carbide powder.
Tungsten carbide powder is widely used in many fields due to its excellent physical and chemical properties: Tungsten carbide powder is the main raw material for the production of cemented carbide. Cemented carbide has the characteristics of high hardness, high wear resistance and high toughness, and is widely used in cutting tools, drilling tools, mining tools and wear-resistant parts. Tungsten carbide powder is also an important raw material powder for preparing high wear-resistant coatings in the field of thermal spraying. Through thermal spraying technology, tungsten carbide powder can be coated on the surface of the substrate to form a coating with excellent wear resistance. Tungsten carbide powder can also be used to manufacture resistance heating elements, metal ceramic materials and as aerospace materials. In addition, it can also be used as a modified additive for NbC-C and TaC-C ternary system carbides, which can reduce the sintering temperature and maintain excellent performance.
Tungsten carbide dust can cause respiratory diseases such as bronchitis and bronchiolitis. Therefore, when working in an environment exposed to tungsten carbide powder, personal protective equipment such as gas masks, dust-proof clothing, gloves and glasses that meet the requirements are required. At the same time, physical examinations should be carried out regularly to ensure the health of workers. Tungsten carbide powder should be stored in a dry, ventilated and cool place, avoiding contact with moisture, oxidants and other items. During transportation, the package should be prevented from damage and leakage to ensure safe transportation. In summary, tungsten carbide powder is a high-quality material with broad application prospects. With the continuous development of science and technology, the application field of tungsten carbide powder will be more extensive, and its preparation technology and product quality will continue to improve.
