The uses and application fields of rare earths 2024-02-07
Rare earth elements are known as "industrial vitamins" and have irreplaceable excellent magnetic, optical, and electrical properties. They play a huge role in improving product performance, increasing product variety, and improving production efficiency. Due to its importanteffect and low usage, rare earths have become an important element in improving product structure, increasing technological content, and promoting industry technological progress. They are widely used in fields such as metallurgy, military, petrochemicals, glass ceramics, agriculture, and new materials.
The role of rare earth catalytic materials in automotive exhaust purification 2022-01-12
At present, the catalysts widely developed and applied in automobile exhaust purification abroad are basically composed of platinum (Pt), rhodium (Rh) and other precious metals. At present, the commonly used platinum rhodium-based precious metal ternary catalysts mainly purify HC and CO through the oxidation of Pt, and purify NOx through the reduction of Rh. Although the catalyst has the advantages of high activity, good purification effect and long life, but the cost is also high, especially the Pt, Rh and other resources are limited. In order to alleviate the contradiction between the supply and demand of Pt, especially Rh, palladium (Pd), which is relatively cheap, has been widely used, and catalysts composed of Pt, Rh and Pd as well as palladium catalysts have been developed
oron carbide: a bulletproof ceramic material with excellent comprehensive performance 2022-01-12
In recent years, advanced ceramics have shown great brilliance in the military arena. With high specific stiffness, high specific strength and chemical inertness in many environments, protective armor made of advanced ceramics is an essential part of the armor system due to its high resistance to intrusion, lightness and comfort.
