Overview of Silicon Nitride

Silicon Nitride (Si₃N₄) is a critical ceramic material renowned for its exceptional mechanical properties, high-temperature resistance, and chemical stability. It is widely used in the fabrication of high-temperature structural components, bearings, cutting tools, and electronic devices. Silicon Nitride can be prepared through methods such as reaction sintering or hot pressing, resulting in two crystalline forms: α-Si₃N₄ and β-Si₃N₄, depending on the production process.

Features of Silicon Nitride

High Hardness and Wear Resistance: Silicon Nitride boasts remarkable hardness and wear resistance, making it ideal for high-performance cutting tools.

Thermal Stability: It maintains excellent mechanical properties at extremely high temperatures, with a maximum usage temperature exceeding 1200°C.

Good Chemical Stability: It shows great resistance to corrosion by most molten metals and acid-base solutions.

Low Density: Compared to metal materials, Silicon Nitride has a lower density, beneficial for reducing the weight of structural components.

Excellent Electrical Insulation Properties: It is a preferred choice for electronic packaging materials.

Specification of Ammonium paratungstate metal powder Tungsten powder CAS11120-25-5

Ammonium Paratungstate Tungsten Powder carries the CAS number 11120-25-5. This material is a vital precursor in making pure tungsten metal and tungsten carbide. Its chemical formula is (NH4)10[H2W12O42]·4H2O. The powder form is fine and usually appears white or slightly yellow. Its color depends on exact purity and any tiny impurities present.

High purity defines this product. Typical purity levels reach 99.95% or better. This is critical for demanding industrial uses. Precise control over particle size is another key feature. Manufacturers offer various standard sizes. Common sizes range from coarse granules down to sub-micron particles. Specific particle size distribution is available to meet customer needs. This powder dissolves well in water. It shows low solubility in most common organic solvents.

Production involves careful crystallization from ammonium tungstate solutions. Further processing includes controlled drying steps. This ensures consistent physical properties batch after batch. The main use is producing tungsten metal powder. This happens through hydrogen reduction furnaces. The resulting tungsten powder is essential. It forms tungsten metal parts via pressing and sintering techniques. It is also the base material for tungsten carbide powder. Tungsten carbide is crucial for hard cutting tools and wear-resistant parts.

Other applications exist. This powder serves in catalysts for certain chemical processes. It finds use in making specialty alloys requiring tungsten. It acts as a flame retardant additive in some plastics and textiles. Proper storage is important. Keep the powder in a cool, dry place. Use sealed containers to prevent moisture absorption. Avoid contact with strong acids or strong oxidizing agents. Handle it carefully. Use appropriate personal protective equipment like gloves and dust masks. This minimizes inhalation or skin contact risks.

Applications of Ammonium paratungstate metal powder Tungsten powder CAS11120-25-5

Ammonium paratungstate (APT) metal powder, CAS 11120-25-5, is a vital starting material. It makes tungsten powder. This tungsten powder is essential for many important products. Its high melting point and strength are key reasons. Tungsten filaments are a major use. These filaments go inside incandescent light bulbs and halogen lamps. They glow brightly when electricity passes through them. The powder is also crucial for making tungsten carbide. Tungsten carbide is incredibly hard. It is used to make cutting tools, mining equipment, and wear-resistant parts. These tools last much longer than regular steel tools.

The powder is used to produce tungsten metal alloys too. Mixing tungsten with other metals creates superalloys. These superalloys withstand extreme heat. They are found in jet engine parts and high-temperature furnaces. The electronics industry relies on this powder. It is used in electrical contacts and electrodes. These components need to handle high currents without melting. They are found in things like welding equipment and high-power switches.

Chemical processes use ammonium paratungstate powder as well. It acts as a catalyst or catalyst material. Catalysts speed up chemical reactions. This helps make various chemicals more efficiently. The powder is involved in sintering processes. Sintering heats powdered material to bond particles together. This makes strong, dense metal parts. Tungsten’s density is another advantage. It is used in weights, counterbalances, and radiation shielding. The powder provides the raw material for these heavy metal applications.

The quality of the starting ammonium paratungstate powder matters greatly. It directly affects the final tungsten powder quality. Consistent particle size and purity are critical. Manufacturers need reliable APT powder suppliers. Good powder ensures the final products meet strict performance standards. This material supports many modern technologies and industries.
