Titanium chromium niobium tantalum quaternary medium-entropy MAX phase ceramic materials as new ceramic materials have attracted widespread attention in the field of materials science.

Phosphorus and potassium fertilizers include plant ash, compound fertilizer, potassium dihydrogen phosphate, and potassium nitrate phosphate fertilizer.

Egg shell, Bone meal and sesaome are the most environmentally friendly phosphorus and potassium fertilizers are available in every household.

In the agricultural field, tripotassium phosphate undoubtedly occupies a pivotal position and is regarded as an indispensable agricultural fertilizer.

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
