Product Information
Niobium crucible is made of high purity metal niobium, which has strong resistance to high temperature and deformation. According to the different processing methods, NB crucible can be divided into four types: stamping, machining, sintering and welding.Niobium crucible has strong resistance to high temperature and deformation, and can be widely used in rare earth smelting, high temperature sintered plate, chemical corrosion resistant vessels, sputtering evaporation vessels and other occasions.
Niobium crucible for stamping
Stamping niobium crucible is the selection of high quality niobium plate or niobium foil, with a suitable mold for single or multiple stamping production, the final production of qualified products. High dimensional precision, relatively high mechanical properties, suitable for the production of small and medium-sized crucible.
Processing niobium crucible
The mechanical processing of niobium crucible is to select high quality niobium rod and eventually produce qualified niobium crucible through turning. The niobium crucible produced by this process has excellent mechanical properties, but wastes a lot of niobium material, so the cost of niobium crucible is relatively high.
Sintered niobium crucible
Sintered niobium crucible is to select appropriate niobium powder, press it through isostatic pressing technology, and then sintered at high vacuum temperature to produce niobium crucible billet, which is then combined with mechanical processing to produce the required size. The process is suitable for the production of medium - large - sized niobium crucible.
Welding niobium crucible
Welding niobium crucible is the suitable size of niobium plate or niobium foil rolling, welding at the joint, welding round plate at the other end of the cylinder, and finally the appropriate surface and weld treatment, size correction, and finally the production of qualified crucible. The process has low production cost and is suitable for the industry where the crucible size requirement is not strict.
