Alumina suspension (Al2O3) - made by Schmitz.
• Grain size from 0.04 to 5 µm
• Water-based (standard)
• pH 7 (pH-neutral version. Suitable e.g. for polishing Si3N4 ceramics. The liquid sinter phase is no longer polished out).
• Anhydrous (for polishing Mg and Zn alloys or coatings)
Of course, our alumina suspensions are agglomerate-free and remain stable in suspension for a long time.
