Magnesium Oxide Material Properties
Magnesium Oxide Ceramic Machining
Magnesium oxide can be machined in green or bisque form before sintering, and to a limited extent in its fully sintered state. In its pre-sintered state, the material is relatively soft and easier to shape, but like many ceramics, it undergoes significant shrinkage—up to 20%—during sintering, which can affect final dimensions. Fully sintered magnesium oxide is very hard and brittle, requiring diamond tools and precision equipment for any post-sintering machining.
Machining Methods and Considerations
- Green or Bisque Machining: Easier to cut and form, suitable for complex shapes before firing.
- Sintering Shrinkage: Expect about 15–20% dimensional reduction during sintering, which impacts tolerance control.
- Post-Sintering Machining: Requires diamond grinding tools due to the material’s hardness and brittleness.
- Fragility: Fully sintered MgO is prone to chipping and fracture if not handled with care during machining.
- Tooling and Time: Machining dense MgO ceramics is time-consuming and requires specialized equipment.
Magnesium Oxide Ceramic Packaging
Magnesium Oxide Ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of the products in their original condition.
