Tungsten, titanium, tritium, osmium, iron, steel, zirconium, chromium, vanadium, tantalum. These metals have very high hardness and are also very rare.
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
As the core component of new energy vehicles, all parties attach great importance to it. This makes people wonder, that is, why has there been no breakthrough so far?
