Introduction
Yttria Stabilized Zirconia (Y – TZP) is the strongest ceramic material offered by Zibo Yiho Wear Ceramics Co., Ltd. Y – TZP is a purely tetragonal phase, fine – grain material, and it represents the pinnacle of our ceramic grinding media lineup. Our Yttria Stabilized Zirconia Grinding Balls, also known as YSZ Grinding Media, are engineered to meet the most demanding grinding and dispersion requirements across a wide range of industries.
Key Features and Advantages
Superior Material Properties
- High Hardness and Strength: YSZ Grinding Balls exhibit high crushing strength and wear resistance. They are made from yttria – stabilized zirconia powder, which gives them the highest flexural strength among all Zirconia – based materials. This high strength ensures that the balls can withstand the rigorous conditions of grinding and dispersion applications without deformation or breakage.
- High Density and Specific Density: With a high density and large specific density, these grinding balls provide excellent impact energy during the grinding process, resulting in more efficient particle size reduction.
- Excellent Wear Resistance and Corrosion Resistance: They are inert to most non – acidic fluids, resistant to rust and corrosion. This makes them suitable for use in a variety of chemical environments, ensuring long – term performance and reliability. The wear loss is extremely low, with a PPM – grade wear loss of ≤1.3g/kg·h, which means less contamination of the ground materials and longer service life compared to other grinding media.
Ideal Bead Characteristics
- Narrow Size Distribution and Perfect Spherical Shape: The Yttria beads are offered with a narrow bead size distribution and perfect spherical shape. This provides superior operational performance during the grinding process, ensuring uniform and consistent grinding results. Although the bead lifetime is dependent on suspension formulations, they are commonly used for extremely long periods of time.
- High Sphericity: With a sphericity of ≥95%, the balls can move smoothly in the grinding equipment, reducing friction and energy consumption.
Wide Range of Applications
Pharmaceutical Industry
In the pharmaceutical industry, where high – purity and contamination – free grinding media are essential, Yttria Stabilized Zirconia Grinding Balls are the ideal choice. They are used for grinding active pharmaceutical ingredients (APIs) to achieve fine particle sizes without introducing unwanted impurities. The contamination – free nature of these balls helps to maintain the purity and efficacy of the pharmaceutical products.
Electronic Ceramic Industry
For the production of electronic ceramics, which require high – precision and high – quality materials, our YSZ Grinding Balls are widely used. They can grind ceramic powders to the desired fine particle sizes, ensuring the excellent electrical and physical properties of the final electronic ceramic products. The high density and wear resistance of the balls contribute to the efficient and stable grinding process in this industry.
Coatings, Inks, and Pigments Industry
In the coatings, inks, and pigments industry, Yttria Stabilized Zirconia Grinding Balls are used to disperse pigments and other components evenly. Their wear resistance and corrosion resistance ensure that the grinding media can withstand the harsh chemical environments in these industries, while their ability to produce fine and uniform dispersions helps to improve the quality and performance of the final products.
Nano and Fine Particle Production
These grinding balls are particularly suitable for nano – particle size production and fine particle size production industries. Their high crushing strength and wear resistance, combined with their low wear loss, make them capable of grinding materials to extremely fine particle sizes without significant contamination. They can handle a wide range of materials, from soft to hard, and from brittle to ductile, to produce the desired fine and nano – scale particles.
