ZYLAB High Purity Zirconia Planetary Mill Jars
Introduction:
The ZYLAB Zirconia Planetary Mill Jar is designed for high-efficiency grinding, mixing, and homogenization in laboratory planetary ball mills. Made from high-purity zirconia (ZrO₂), this jar offers exceptional hardness, superior wear resistance, and outstanding chemical stability. It ensures minimal contamination during milling, making it ideal for precise material processing in research and industrial applications.
Pure zirconia is a white solid with a theoretical density of 5.89 g/cm³ and a melting point of 2715°C. Depending on impurities or dopants, it may appear gray, light yellow, or other colors. Compared with alumina jars, the zirconia jar provides even higher mechanical strength and lower abrasion loss, ensuring longer service life and cleaner results.
The ZYLAB Zirconia Planetary Milling Jar adopts a large-radius R-corner design at the bottom and a flat sealing gasket structure at the jar mouth, providing smooth rotation, excellent sealing, and stable performance during high-speed operation.

In addition to zirconia, ZYLAB also offers planetary milling jars made from a variety of other materials, including stainless steel, alumina, agate, cemented carbide, and silicon nitride. Each type is carefully designed to meet different research and material processing requirements.
