Magnesium Oxide Crucible - MgO Crucible

Magnesium Oxide Crucible is made from high-purity magnesia ceramic, offering excellent thermal stability and resistance to chemical attack in high-temperature environments. It performs reliably in applications involving molten metals, oxides, and aggressive slags, especially at temperatures exceeding 2000°C. With low thermal conductivity and a high melting point, this crucible is ideal for use in vacuum systems, metal processing, and ceramic sintering. Both cylindrical and conical shapes are available, and custom dimensions can be produced to meet specific lab or industrial needs. Heeger Materials (HM) provides durable MgO crucibles for consistent performance in demanding thermal and chemical environments.
