Niobium Crucible

Description

With high purity (≥99.9%), high level of resistance and excellent formability, our niobium crucible is appropriate for manufacturing synthetic polycrystalline diamonds. It is often used for high-pressure and high-temperature synthesis.
In different forms, niobium crucible can be used in the field of synthetic diamonds, fiber optic or architectural glass, chemical engineering, superconductors, thin-film, reactors and high temperature vacuum furnaces and sodium vapor lamps.

Package and Transportation

We pack niobium crucible in plywood case and send them by ocean or air.
