Six Major Uses of Silver Nitrate Powder

  I. Introduction N-Methyl-Pyrrolidone (NMP)   is a product with a wide range of applications. In the previous issue, we discussed its use in the lithium battery industry. This issue will focus on its applications in the semiconductor and electronics industry. II. Main Applications of NMP in the Semiconductor and Electronics Industry 1. Wafer Cleaning with NMP During semiconductor manufacturing, organic contaminants and fine dust easily adhere to the wafer surface. Due to its excellent solubility, NMP can effectively remove grease, flux residues, and metal ions from the wafer surface, ensuring cleanliness and improving chip yield. 2. Photoresist Stripping Photoresist is a key material in semiconductor manufacturing, but after exposure and etching, the remaining photoresist must be completely removed. NMP efficiently dissolves photoresist without damaging the silicon wafer surface, making it widely used in wet photoresist stripping processes. 3. Electronic-Grade High-Purit...

  Introduction: The Key Role of NMP in the Lithium Battery Industry N-Methyl-pyrrolidone (NMP, CAS: 872-50-4) is a polar aprotic solvent widely used in the preparation of cathode slurries for lithium-ion batteries (LIBs). Due to its excellent solubility, low volatility, and high boiling point, NMP efficiently dissolves polyvinylidene fluoride (PVDF), ensuring uniform coating of active materials on current collectors and enhancing battery performance. However, as the lithium battery industry rapidly advances, optimizing NMP usage, increasing recovery rates, reducing costs, and minimizing environmental impact have become major research focuses. 1. The Role of NMP in Lithium-Ion Batteries During lithium battery manufacturing, NMP is mainly used in the preparation of cathode slurries to ensure uniform dispersion of active materials, conductive agents, and binders, forming a stable electrode structure. Its key roles include: Dissolving PVDF binder : NMP effectively dissolves PVDF, allow...
