Magnesium aluminate spinel (MgAl2O4) for transparent ceramics
Baikowski® develops high-purity magnesium aluminate spinel (MgAl2O4) powders engineered for
transparent ceramic components where optical performance must be combined with robust mechanical behavior.
In addition to optical windows and protection components, transparent spinel can also be used as a robust ceramic for detector protection in demanding environments.

FAQ – Spinel (MgAl2O4)
Q- Why is spinel used for transparent ceramics?
A- Spinel can combine optical transmission with mechanical robustness, which makes it suitable for protection windows and optical parts used in demanding environments.
Q-Why spinel for demanding optical components?
- Optical clarity with reduced scattering for transparent parts.
- Defect control to minimize black/white spots and other visual imperfections.
- Mechanical robustness for components exposed to impact, abrasion, or harsh handling.
- Process consistency supported by tight control of purity and powder engineering.
Q- Can Baikowski® support grade selection and customization?
A- Yes—our team can recommend the right spinel grade and support customization to match your process constraints and application requirements.
