Rare earth elements are known as a treasure trove of new materials and "industrial vitamins" due to their unique 4f electronic structure. Rare earth oxide powders are a hot spot in the current development of rare earth materials. Particle size distribution is a very important performance indicator ... Read More

Rare earth oxyfluorides have the advantages of rare earth oxides and rare earth fluorides, that is, rare earth oxyfluorides have lower phonon energy than rare earth oxides and better thermal stability and durability than rare earth fluorides. Currently, research on rare earth oxyfluorides has become ... Read More

Magnesium and its alloys are known as "green engineering materials of the 21st century" because of their lightweight, biodegradable and recyclable characteristics. Magnesium alloys have excellent thermal conductivity, high specific strength and specific stiffness, good mechanical properties and ... Read More

Aluminum alloy is relatively active. Under normal atmospheric conditions, an oxide film composed of α-Al2O3 and β-Al2O3 will naturally form on the surface, but the thickness is relatively thin. This makes the aluminum alloy matrix have a certain corrosion resistance in normal atmospheric environment... Read More

Coal is a fossil that has been subjected to geological action for a long time and contains a certain amount of rare earth elements. When coal is burned, the rare earth elements in it are enriched in the coal ash. Therefore, using coal ash as a raw material to extract high-value rare earth elements ... Read More

Rare earth technology workers have long been committed to using rare earth citrate in PVC heat stabilizers and rubber additives, and have achieved many satisfactory results. Rare earth citrate can also achieve good results in animal experiments. In the experiment, rare earth citrate was added to ... Read More

Due to its unique physical and chemical properties, cerium dioxide is widely used in the polishing fields of glass, semiconductors and jewelry, and has attracted extensive attention from researchers in recent decades. Related studies have shown that the addition of F to polishing powder plays an ... Read More

Hydrogen energy is regarded as the clean energy with the greatest development potential in the 21st century, but its large-scale use is restricted by problems such as storage difficulties and transportation risks. Ammonia is considered to be the most promising hydrogen carrier of the next generation ... Read More

Since the 1960s, rare earth compounds have been discovered to have a series of special pharmacological effects. Rare earth ions have been found to be excellent antagonists of Ca2+, with sedative and analgesic effects. They are widely used in the treatment of burns, inflammation, skin diseases, ... Read More

Titanium alloys are used in aerospace, shipbuilding, biomedicine and other fields due to their excellent properties such as low density, high specific strength, fatigue resistance and wear resistance. However, with the continuous expansion and deepening of its application fields, the performance of ... Read More
