High-purity praseodymium ingots are produced using vacuum induction melting (VIM) or electron beam melting (EBM) to remove impurities and ensure chemical uniformity. Each batch is tested with GDMS and ICP-MS to confirm purity, chemical consistency, and low impurity levels before further processing.
The formed slabs are hot-forged or hot-rolled to increase density and refine the grain structure. This process removes internal voids and ensures mechanical strength and uniform sputtering behavior.
Targets are machined with tight tolerances in diameter, thickness, and flatness to meet exact customer and equipment requirements. Accurate machining ensures stable sputtering rates and compatibility with various coating systems.
Final surface finishing and polishing reduce surface roughness to below 2 μm, creating a clean, oxide-free surface that improves sputtering efficiency and film uniformity.
When needed, praseodymium targets can be bonded to copper or molybdenum backing plates using indium soldering or diffusion bonding.
Each target is inspected for dimensions, flatness, grain structure, and surface quality before shipment. Approved products are vacuum-sealed with desiccant or argon-filled, and each order includes a Certificate of Analysis (COA) and full quality documentation.
