Naphthalenesulfonic acid is an important chemical intermediate based on a naphthalene ring structure linked with sulfonic acid groups. It is widely used in the production of dyes, pharmaceuticals, pesticides, concrete water reducers, and other chemical products. During the manufacturing process…

Battery black mass, obtained after crushing and sorting spent lithium-ion battery cathode materials such as lithium nickel cobalt manganese oxide (NCM) and lithium cobalt oxide (LCO), contains valuable metals including nickel, cobalt, lithium, and manganese. However, these metals are closely…

In industries such as pharmaceuticals, pesticides, polyurethane synthetic leather, aramid fiber production, and electronic chemicals, N,N-Dimethylformamide (DMF) is widely used as an important solvent. However, DMF is completely miscible with water in any proportion and has a high boiling point…

Scandium is a silvery-white rare metal that plays an irreplaceable role in advanced fields such as aerospace, solid oxide fuel cells (SOFCs), metal halide lamps, and laser crystals. However, scandium is highly dispersed in nature and difficult to concentrate. Its…

As global investment in superconducting material research and development continues to increase, niobium-titanium (Nb-Ti) alloy, currently the only superconducting material that has achieved large-scale commercial application, is entering a period of rapidly growing demand. From MRI medical equipment and particle…

In high-end industries such as aerospace, defense, and medical manufacturing, titanium alloys are often regarded as the “backbone of modern metals.” From aircraft engine blades and landing gear to airframe structures and fasteners, titanium alloys have become indispensable materials due…
