Tungsten slurry is composed of tungsten powder, inorganic binder phase and organic carrier, which has extremely high melting point, good conductivity and thermal conductivity. It is widely used in high temperature co-firing technology. Tungsten powder provides the premise for good sealing. The role of inorganic binder phase is to help sinter and provide sealing strength. The organic carrier is divided into three parts: resin, solvent and additive. Surfactant, leveling agent, antifoaming agents and other organic additives. Applications Melting point of…

Waste tungsten powder is a tungsten powder that cannot meet the requirements of the follow-up production dingally and may be recycled during production, logistics transportation, storage and use. Recycling waste tungsten powder can improve economic efficiency and reduce environmental pollution. In the process of powder metallurgy, a lot of waste tungsten powder is produced for various reasons. In the process of logistics transportation, storage and use, oxidation may occur, or other substances, it may be adulterated to cause insufficient purity,…

Ready to press tungsten powder is a kind of powder used for cemented carbide sintering. It has excellent physical and chemical properties, good fluidity and compressibility, high chemical content and good carbon control. Characteristics Ready to press tungsten powder has stable apparent density, good liquidity and compressibility. Its chemical content is high, and amount of carbon control is good. Applications Ready to press tungsten powder is a raw material sintered in cemented carbide. During sintering, a series of physicochemical processes…

The scandium oxide of nano scandium oxide doped tungsten powder is evenly distributed and has small particles. It can produce excellent performance of the scandium tungsten matrix, improve the anti-ion bombardment performance, and help to improve cathode emission uniformity. Preparation Nano scandium oxide doped tungsten powder can be liquid-solid doping method by the decomposition of the reduction process. Scandium oxide evenly covered the surface of tungsten particles, pinning the role of inhibiting grain growth. Applications Nano scandium oxide doped tungsten…

Tungsten aluminum powder is a kind of doped tungsten powder, which is prepared by tungsten powder mixed with aluminum. Its aluminum content is very low, and the oxygen content can be determined by the pulse heating coulometry. Aluminum is volatile at high temperatures, which may affect the determination of oxygen content. So It usually adopts the pulse heating coulombic oxygen method, this method is accurate, reliable, sensitivity and the minimum detection limit of the instrument can meet the production and…

Rare earth doped tungsten powder is a kind of tungsten powder doped with rare earth elements. It has a finer grain size, higher purity, and a regular cubic shape of powder, with higher potassium content. The doped tungsten products prepared with rare earth doped tungsten powder have excellent properties at high temperature and normal temperature. Under the condition of the same reduction process, rare earth elements can reduce the reduction rate of doped tungsten powder, split time later. In the…

Scandium doped tungsten powder is Sc2O3 doped tungsten powder, which is prepared by liquid-solid doping. It is used in the preparation of scandium – containing tungsten cathode, which is thermionic emission uniformity, strong ability to resist ion bombardment. Sc2O3 powder was evenly adhered to the surface and crack of the doped tungsten powder, and Sc2O3 was evenly covered in the tungsten particles, and increased with the tungsten contact surface, increasing the binding force of scandium and tungsten. Scandium tungsten powder…

Spherical tungsten carbide powder has the uniqueness of the preparation technology and excellent performance, is a high-tech materials, thermal spraying spherical appearance, internal grain fine powder, high hardness and better the wear resistance of the coating, powder, good fluidity, etc. Characteristic Compared with the common polygonal tungsten carbide powder, the spherical tungsten carbide powder has two remarkable characteristics: first, the appearance is spherical, the powder fluidity is good, and the surface quality of the workpiece is high. The second is…
