Molybdenum Crucibles

Product Description

Molybdenum Crucibles – High-Temperature Metal Crucibles for Furnace & Crystal Growth

Molybdenum crucibles are precision-engineered metal containers designed for ultra-high temperature applications, especially in vacuum and inert atmospheres. Known for their exceptional thermal conductivity, high melting point (2622°C), and mechanical strength, molybdenum crucibles are the material of choice in crystal growth, metallurgy, and high-temperature furnaces.

Molybdenum crucibles can be used to conduct tests with many chemical solutions. At room temperatures, they are non-reactive to hydrochloric acid, hydrofluoric acid and alkali solutions, but dissolve in nitric acid, concentrated sulphuric acid and aqua regia. They oxidise at temperatures between 400 °C – 800 °C under oxidising atmosphere and resulting in molybdenum vaporising. Therefore, it is recommended that for high temperatures, around 2000 °C, experiments with Molybdenum Crucibles should be performed in an inert environment.

At M-Kube, we supply high-purity molybdenum crucibles across Australia, catering to research laboratories, crystal growth facilities, and metal processing industries that demand high performance and durability under extreme heat.

Custom Molybdenum Crucibles Engineered for Precision and Performance

We provide both standard and custom-made molybdenum crucibles to suit specific temperature, atmosphere, and dimensional requirements. Whether you’re working in semiconductor R&D or metal alloy production, our crucibles can be tailored to your exact process needs.

Customisation options include:

• Cylindrical, conical, and stepped crucibles
• Precision machining for vacuum chamber fit
• Thin-wall or thick-wall configurations
• Welded or seamless construction
• Surface polishing or coating options (e.g., ZrO₂, BN)

As a trusted molybdenum crucible supplier in Australia, M-Kube supports fast-turnaround custom orders and long-term procurement planning.

Thermal, Mechanical, and Chemical Properties of Mo Crucibles

Molybdenum is a refractory metal offering superior performance in thermal and mechanical stability:

• High Melting point 2622°C
• High Boiling point 4639°C
• Excellent dimensional stability at high temperatures
• Good thermal and electrical conductivity
• Low coefficient of thermal expansion
• Outstanding resistance to corrosion in vacuum and inert gas
• High strength-to-weight ratio and machinability

These attributes make molybdenum crucibles ideal for demanding thermal processes and crystal growth applications.

Applications of Molybdenum Crucibles

Molybdenum crucibles are widely used in Australian industries and research sectors where performance under extreme conditions is critical:

• Sapphire and rare-earth crystal growth (e.g., LED production)
• Vacuum melting of metals and alloys
• High-temperature nuclear fuel sintering, capacitor sintering and powder metallurgy
• Semiconductor wafer production
• Furnace parts for laboratory and industrial heating systems
• Evaporation of metals in PVD coating systems
