The dimensions listed above are for reference only. Please contact us if you need tight tolerance.

Note: For solid state electrolyte, using a MgO block in the crucible makes it easier to take out the sintered pellet.

MgO blocks are considered as consumables which are not covered by warranty. 

You can buy a whole set of MgO crucibles with cover and block for sintering of green pellets of 1 inch (25.4mm) or less, click here.

Introduction and Applications

Magnesium Oxide Crucibles are good for the application of ultra high temperature processes up to 4000 °F (2200 °C). MgO crucible is a better alternative to Alumina (Al2O3) crucibles due to their superior chemical resistance and its inertness to metals, slags and superconductor compounds.

When MgO crucibles are used in lithium solid state electrolyte synthesis or sintering, MgO has its own unique advantage of not reacting with Lithium unlike Al2O3 crucibles, therefore it maintains the lithium vapor pressure better without causing access lithium loss in the solid state electrolyte.

Other applications include:

* Superconductor material processing

* Beta Alumina Processing

* Dielectric, piezoelectric, pyroelectric material processing

* Nickel based super alloy processing

* Plutonium and Uranium related material processing
