Tungsten, titanium, tritium, osmium, iron, steel, zirconium, chromium, vanadium, tantalum. These metals have very high hardness and are also very rare.

zinc sulfide is widely studied and used among II-VI compounds. One of the materials.

The four main categories are gas, liquid, viscous (grease), and solid. When some unsuitable cases, we often turn to solid lubricants.

Chromium, chemical symbol Cr, atomic number 24, atomic weight 51.9961, belongs to Group VIB in the periodic table of elements.

The microstructure of alumina powder is closely related to its performance. Factors such as its crystal form, particle size, morphology, and distribution will affect its application fields and performance.

Silica aerogel has many unique properties in the three-dimensional nanonetwork structure. It has broad application prospects in optics, heat, acoustics, microelectronics, high-power lasers, and other fields. It is another new type of silicon compound func

Silica aerogel has many unique properties in the three-dimensional nanonetwork structure.

New type of screening equipment—the calcium stearate ultrasonic vibrating screen—is gradually attracting attention and favor from the industry.

Nano zinc manganese ferrite, as a nanoscale soft magnetic material, shows even better performance. Its unique nanostructure gives it higher magnetic permeability, lower coercivity and better magnetic stability, making it stand out in the field of soft mag

At high temperatures, potassium silicate can quickly form a dense molten layer that cuts off the oxygen supply, effectively preventing the spread of fire.
