What is a Zirconia Ball?
Zirconia balls are high-performance ceramic grinding media made from high-purity zirconia powder through cold isostatic pressing and high-temperature sintering. With high density, hardness, and excellent wear resistance, they are ideal for precision grinding and dispersion applications. Thanks to their high toughness and ultra-low wear, zirconia balls are widely used in industries such as lithium battery materials, electronic ceramics, magnetic materials, pharmaceuticals, food, high-end pigments, and inks-helping users achieve higher efficiency, better product purity, and lower operating costs.
Product Name: Zirconia Ball
Technical parameters focus
Zirconia Grinding Balls:

Temperature resistance: up to 1000°C+
Size range: 0.3 mm-30 mm
Shape: highly spherical with excellent roundness
Material Composition:
1.Main raw material: High-purity zirconia (ZrO2)
2.Typical formulation: Partially stabilized zirconia (PSZ) or fully stabilized zirconia (FSZ)
3.Typical content: Zirconia content around 92%-95%, with a small amount of stabilizers such as Y2O3
Production Process:
Selection of high-purity powder----Cold isostatic pressing (CIP) forming----High-temperature sintering (commonly at 1400-1600°C)
In summary, zirconia balls are the ideal solution for modern fine grinding and high-purity production, thanks to their high density, hardness, low wear, and excellent chemical stability. They are widely applied in lithium batteries, magnetic materials, electronic ceramics, food, pharmaceuticals, and chemical inks, helping to increase efficiency, reduce costs, and ensure quality.

Zirconia balls are advanced ceramic grinding media that combine high density and toughness, produced from high-purity zirconia using strict manufacturing processes. They are designed for demanding grinding environments.
Advantages
Precision grinding and multi-step quality inspection
High density (~6.0 g/cm³) for efficient grinding
Ultra-low wear for extended media and equipment life
Superior toughness reduces breakage
Corrosion resistance keeps materials contamination-free
Multiple sizes available to meet different process requirements
Widely used in lithium batteries, electronic ceramics, magnetic materials, chemicals, inks, food, and pharmaceuticals
Thanks to their high density and hardness, zirconia balls enable faster particle size reduction and more uniform dispersion in mills and mixing equipment.
Zirconia balls have become indispensable in new energy and advanced manufacturing as efficient grinding media. In lithium battery cathode and anode materials, electronic ceramic powders, magnetic materials, and pharmaceutical processing, their combination of high density, toughness, and low wear provides stable and reliable performance. Especially in food and pharmaceutical industries, their high purity and chemical inertness meet strict production standards, helping companies achieve better product quality and higher productivity.
