Zirconia Ceramic Rod/Bar Features
- High Wear Resistance and Toughness: Made from high-purity microcrystalline zirconia powder, the rod is sintered at 1550°C. Its fine crystalline structure and reduced defects, such as micro-cracks, result in superior wear resistance and enhanced toughness.
- High Density and Hardness: The rod/bar is formed using high-pressure isostatic pressing, which ensures uniform compression of the powder. This process minimizes gaps between particles, making the crystalline structure more stable and resulting in higher density and hardness.
- Exceptional Stability: Zirconia ceramic rods/bars are made from zirconia powder, an inorganic, non-metallic material that is chemically inert and highly resistant to reactions with most substances. This gives the rods excellent weather resistance and long-lasting stability in extreme conditions.
- Outstanding Corrosion Resistance: Zirconia ceramic rods/bars offer unique properties that metal materials do not, particularly resistance to acid and alkali corrosion. They are commonly used in highly corrosive environments, such as pumps, valves, and bearings, due to their superior corrosion resistance.
Zirconia Ceramic Rod/Bar Applications
- Precision Grinding Equipment: Used in ultrafine grinding for various industries, ensuring high wear resistance and durability.

Zirconia Ceramic Machining
Zirconia, a high-performance ceramic, is known for its toughness, hardness, and wear resistance, making it ideal for applications requiring high mechanical strength and thermal stability. However, machining zirconia can be challenging due to its hardness and toughness, requiring different methods depending on its processing state.
Machining Zirconia in Different States:
- Green and Biscuit Form: Easier to machine before sintering, but tight tolerances can’t be maintained due to shrinkage during sintering.
- Fully Sintered Zirconia: Becomes hard and dense, requiring diamond grinding or cutting for precise shapes.
Common Machining Methods:
- CNC Machining: Used for complex shapes, often with diamond tools.
- Diamond Grinding: For precise dimensions and surface finish.
- Diamond Cutting and Sawing: Special diamond tools prevent cracking.
- Polishing: Smooths surfaces, especially for medical or precision applications.
Zirconia Ceramic Packaging
Zirconia 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 products in their original condition.
