Characteristics of Nickel-Niobium Targets
Shapes: Planar targets, custom-shaped targets
Purity: 3N
Dimensions: Machined according to drawings or custom-made
Method for Preparing Nickel-Niobium Alloy Targets
Raw Material Preparation: Select high-purity nickel and niobium powders as raw materials, ensuring their purity meets the requirements for target fabrication (e.g., purities exceeding 99.9% for both).
Powder Mixing: Precisely weigh the nickel and niobium powders according to the designed alloy composition ratio and thoroughly mix them using appropriate equipment. To ensure homogeneity, ball milling may be employed, with carefully controlled milling times and ball-to-powder ratios.
Compaction/Forming: Load the uniformly mixed powder into a mold and compact it using methods such as cold isostatic pressing (CIP) or hot isostatic pressing (HIP) to produce a target blank with the required density and strength. CIP allows for initial shaping at lower pressures, while HIP further enhances the density of the blank through high-temperature, high-pressure processing.
Sintering: Place the compacted target blank into a vacuum furnace for sintering to eliminate inter-particle voids and improve the target's density and performance. Sintering temperature and duration are critical parameters; typically, temperatures range from 1000°C to 1500°C, and holding times vary from a few hours to several tens of hours, depending on the specific composition and dimensions of the target.
Machining: Subject the sintered target to machining processes-such as turning and grinding-to achieve the specified dimensions and surface finish requirements.
