Magnesia Crucibles – High-Temperature MgO Ceramic Crucibles
Magnesia crucibles, made from high-purity magnesium oxide (MgO), are engineered for applications requiring resistance to extremely high temperatures and basic (alkaline) environments. With a melting point above 2800°C and an operating temperature of about 2000°C and strong chemical stability, they are ideal for materials testing, metal processing, and fusion analysis.
At M-Kube, we supply high-temperature magnesia crucibles in Australia for laboratories, metallurgy, ceramics, and research facilities. Our magnesia crucibles offer excellent performance in thermal processing where alumina or silica may not be suitable.
Custom and Standard Magnesia Crucibles for Extreme Heat Applications
We provide a variety of standard magnesia crucibles as well as custom-made sizes to meet unique furnace or experimental requirements. These crucibles are available in multiple shapes and wall thicknesses, with excellent structural integrity even at extreme temperatures.
MgO crucibles are available in various purity and different ranges from clay to yttria and alumina depending on the application. These high temperature resistance crucibles can work under different atmospheres with the stability at 24000C in air, 17000C in reducing atmospheres, 16000C in a vacuum, and 14000C in hydrogen.
Customisation options include:
- Cylindrical, conical, or tapered designs
- Custom heights, diameters, and wall thicknesses
- Open or closed-bottom configurations
- Polished or rough interior surfaces
- Batch or prototype production
As a reliable magnesia crucible supplier in Australia, we work closely with labs and manufacturers to ensure consistent performance, material compatibility, and short delivery times.

Key Properties of MgO Crucibles – Thermal & Chemical Resistance
Magnesia crucibles are valued for their outstanding thermal and chemical performance under harsh process conditions:
- Extreme temperature resistance up to 2400°C and Operating temperature of about 2000°C
- Superior stability in basic and alkaline environments
- Low reactivity with metals and refractory materials
- High thermal conductivity and resistance to thermal shock
- Good electrical insulation properties at high temperatures
- Low porosity and high density
These properties make magnesia an ideal material for demanding analytical and high-temperature processes.
Applications of Magnesia Crucibles
Our MgO crucibles are widely used across various Australian industries and research institutes that deal with high-heat, corrosive, or alkaline conditions:
- Fusion flux analysis in mining and minerals labs
- Metallurgical sample preparation
- Rare earth and superalloy processing
- Thermal treatment of alkaline earth metals
- Crucible-based experiments in materials research
- Sintering and ash content testing
