Product Description
Engineered for planetary ball mills, these jars exhibit 10x longer service life than alumina counterparts. The tetragonal phase stabilization prevents crack propagation, while our proprietary surface finishing (Ra ≤0.05μm) minimizes sample adhesion. Each unit ships with a Certificate of Conformity including batch-specific density measurements (Archimedes' principle) and ICP-MS contamination reports showing <50ppb metallic impurities.
Zirconia planetary grinding jar is a high performance laboratory abrasive equipment with the following advantages: High hardness and wear resistance: Zirconia has extremely high hardness and wear resistance, and can effectively maintain its shape and size during high-intensity run-in process, thus providing a more stable and consistent grinding effect. High corrosion resistance: Zirconia has strong corrosion resistance and can be used in harsh environments such as high acid, high alkali and high temperature, avoiding the corrosion problems that occur in the use of traditional ball mill tanks. High temperature stability: Zirconia has a high melting point, can be ground at high temperatures, and has good heat conductivity, can effectively reduce the heat generated in the grinding process. Low wear: Zirconia wears less during high-intensity run-in and does not create additional contamination and residue on the ground sample.
Zirconia grinding tank is mainly used for high-precision sample grinding and mixing, widely used in chemical, pharmaceutical, food, natural gas and other fields. It can be used for grinding and mixing various materials, such as ceramics, glass, metals, plastics, cellulose, etc. In addition, zirconia grinding tank can also be used for sample preparation, quality control, material characterization and other aspects of experimental research.
