Tantalum crucible and processing parts

Because of its high temperature resistance, strong deformation resistance and corrosion resistance, tantalum crucibles are generally used for rare earth metal smelting, induction furnace heating elements, special glass smelting, high-temperature sintering electrolytic capacitor anodes, chemical corrosion-resistant containers and Sputtering and evaporation containers, etc. GOOLEE can produce crucibles according to customer requirements, and can also design and improve crucibles according to customer production requirements.
