Niobium Foil/Strip/Ribbon Production Process
Niobium foil, strip, and ribbon are made of high-purity niobium and niobium alloy ingots through hot rolling, cold rolling, and annealing to achieve the desired thickness, strength, and ductility. Additional treatments, such as polishing and chemical etching, may be applied to meet specific application requirements. Here is the typical production process:
- Raw Material Selection: Niobium ingots or powder are selected based on purity and quality requirements.
- Melting and Casting: Niobium is melted in a vacuum or inert gas atmosphere and cast into ingots.
- Hot Rolling: The ingot is heated and passed through rollers to reduce the thickness and achieve the desired shape.
- Cold Rolling: Further reduction of thickness is achieved at room temperature, improving the material’s surface finish and mechanical properties.
- Annealing: The material is heat-treated to relieve internal stresses and improve ductility.
- Pickling and Polishing: The surface is cleaned using chemical treatments to remove oxides and improve appearance.
- Final Cutting: The material is cut into foil, strip, or ribbon forms, depending on the specific application requirements.
Niobium Foil/Strip/Ribbon Applications
- Electronics Industry: Niobium foil/strip/ribbon is often used in microelectronics, silicon wafer manufacturing, flat panel displays, and storage technology.
