Doped Molybdenum Wire
Doped molybdenum wire is a high-performance metallic filament engineered with trace additives such as potassium (K), silicon (Si), aluminum (Al), or rare earth oxides like lanthanum (La₂O₃) and yttrium (Y₂O₃). These dopants significantly enhance the wire’s recrystallization temperature, oxidation resistance, and mechanical stability at high temperatures, making it an ideal material for demanding industrial and electronic applications.
1.Key Features
High Recrystallization Temperature: Improved grain stability prevents brittleness and deformation at elevated temperatures.
Excellent Creep Resistance: Maintains structural integrity under long-term thermal stress.
Low Vapor Pressure: Suitable for high-vacuum and clean-room environments.
Superior Ductility and Drawability: Supports ultra-fine diameters and complex forming.
Stable Electrical Performance: Ensures consistent current-carrying capability and arc initiation.
