Like tungsten carbide powder (WC powder), ditungsten carbide is also a compound composed of the refractory metal tungsten and the non-metallic element carbon. Its English name is tungsten carbide, with the chemical formula W₂C, and it features a hexagonal close-packed (hcp) crystal structure. Due to slight differences in the crystal structures of WC powder and W₂C powder, their physical and chemical properties, as well as their applications, are also different. Note: The crystal structure of WC can be either a simple hexagonal lattice or a face-centered cubic lattice.

In the vast expanse of cosmic exploration and the graceful flight through blue skies, the aerospace industry demands materials with near-exacting performance standards. From the structural framework of aircraft to the intricate internal instruments, every component must exhibit high strength, low density, high-temperature resistance, and corrosion resistance to ensure safe and stable operation in extreme and hazardous environments. Among these critical materials, high-density tungsten alloy counterweight blocks stand out as unassuming yet indispensable heroes, playing an irreplaceable role in maintaining the balance and stability of flight vehicles.

In the complex structure of an automobile, a seemingly minor yet critical component—the counterweight block—plays a vital role. Though small, it is closely linked to the vehicle’s stability and handling, serving as an unsung hero in ensuring driving safety and comfort.

High-density tungsten alloy, primarily composed of tungsten (typically 85% to 99%) with added metals like nickel, iron, copper, or cobalt, is valued for its high density, strength, corrosion resistance, and wear resistance, making it essential across various fields.

High-density tungsten alloy counterweight blocks, with their excellent properties such as high density, high strength, and high hardness, have wide and critical applications in the aerospace field, as detailed below:

High-density tungsten alloy counterweight blocks, with densities typically ranging from 16.5 to 19.0 g/cm³, along with excellent mechanical properties and stability, play a critical role in adjusting center of gravity and balancing loads across various fields.

Like cobalt tungstate (CoWO₄) and nickel tungstate (NiWO₄), ferrous tungstate is an inorganic compound composed of a transition metal, a Group VIII element, and a non-metal element, exhibiting excellent physicochemical properties and wide applications in the chemical industry. Note: Iron, cobalt, and nickel, known as iron-series elements, are all from the fourth period and Group VIII, with atomic numbers 26, 27, and 28, respectively. Their properties are similar, and they all display ferromagnetism.

Tungsten crucible is a high-temperature resistant vessel made from high-purity tungsten powder (tungsten content >99.95%) through precise powder metallurgy and forming techniques. It maintains structural integrity and functional stability even in high-temperature environments, with its technological level influencing the precision of cutting-edge processes in fields like high-end crystal growth and special material smelting.

Silicotungstic acid, a key member of the polyoxometalate family, showcases significant application potential in materials science, chemical engineering, and biomedicine due to its unique molecular structure and excellent chemical properties. It is an inorganic compound composed of tungsten, silicon, hydrogen, and oxygen, with the molecular formula H₄[Si(W₃O₁₀)₄]·nH₂O and CAS number 12027-38-2.

In the field of advanced materials, tungsten niobium alloy, a typical refractory metal composite, is gaining prominence as a critical foundational material in strategic sectors such as aerospace and high-end equipment manufacturing.
