Features of Zirconia Grinding Media:
Ultra low wear loss as a result of the transformation-toughening mechanism unique
to the yttria stabilized zirconia material system.
Higher grinding efficiency and reduced grinding time due to zirconia¡¯s higher
density
Most durable grinding material, reducing operational cost in the long run.
Wear rate substantially lower than Al2O3, ZrSiO4 and MgO-ZrO2 grinding media. Free
of contamination.
Suitable for high velocity operations and wet grinding operations.
Applications of Zirconia Grinding Media:
Iron and chrome based magnetic materials (for audio, video, recording
tapes) and other magnetic, dielectric, piezoelectric materials.
Electronic-grade ceramics (ferroelectric, piezoelectric, dielectric,
capacitors, sensors, etc.), advanced structural ceramics, and other
ceramic ingredients.
Nanostructured and superfine powders.
Toner materials for photocopiers and laser printers.
Inks, dyes, paint, pigments and coating materials.
Pharmaceutical, dental, cosmetic, and foodstuffs.
High purity advanced ceramic materials, frits, and glazes.
Agrochemicals, calcium carbonates, and other minerals
