Product Description

Yttria Stabilized Zirconia Grinding Jar: Ultra-Hard Grinding Surface for Longer Lifespan

What is Yttria Stabilized Zirconia?

Key Characteristics of Yttria Stabilized Zirconia Grinding Jars

1. High Density and Hardness: With a density of 6.05 g/cm³ and hardness exceeding 1350 HV, YSZ grinding jars are significantly harder than traditional materials like steel and alumina. This makes them highly resistant to wear and tear.
2. Chemical and Thermal Stability: YSZ jars exhibit remarkable resistance to corrosive chemicals and extreme temperatures, ensuring longevity even under rigorous conditions.
3. Low Contamination: The ultra-hard surface of YSZ jars minimizes material contamination during grinding, preserving the purity of the processed materials.
4. Impact and Wear Resistance: The robust construction of YSZ jars allows them to withstand high-impact forces and abrasive environments, extending their service life.

Applications of Yttria Stabilized Zirconia Grinding Jars

1. Mineral Dressing Processes: YSZ jars are used to process minerals into fine powders for further refinement and analysis.
2. Ceramics and Pyrotechnics: In the manufacturing of ceramics and pyrotechnics, YSZ jars help achieve the desired particle size and consistency.
3. Pharmaceuticals: The inert nature of YSZ prevents reactions with active drug ingredients, maintaining the integrity of pharmaceutical products.
4. Materials Science: YSZ jars are crucial in pulverizing metal oxides for powder metallurgy and advanced ceramics.
5. Paints and Pigments: In the paint industry, YSZ jars grind pigments without contamination, ensuring the purity and quality of the final product.

FAQ

1. What is a ball mill jar?

A ball mill jar is a cylindrical container used in ball milling processes to grind, mix, or blend materials using grinding media (such as balls or beads). These jars are commonly used in laboratories, industrial settings, and hobbyist applications for material processing.

2. What materials are ball mill jars made of?

Ball mill jars are typically made from:

Ceramic (Alumina, Zirconia) – High wear resistance, chemically inert.

Stainless Steel – Durable, suitable for heavy-duty grinding.

Nylon, Polyurethane, or PTFE – Non-contaminating, ideal for sensitive materials.

Glass – Transparent, good for observing the milling process but less durable.

3. What sizes are available for ball mill jars?

Ball mill jars come in various sizes, ranging from small laboratory sizes (100 mL to 1 L) to larger industrial sizes (up to 20 L or more). The choice depends on the required batch size and milling capacity.
