Critical for high-efficiency grinding and dispersion of cathode materials (lithium iron phosphate, ternary precursors), silicon anodes, and solid-state electrolytes, achieving nano-scale particle size with minimal contamination.
Used for fine grinding of rare earth magnets (neodymium-iron-boron, ferrite) and magnetic recording media, delivering superior wear resistance and maintaining product purity.
Applied in grinding and dispersion of structural ceramics, electronic ceramics, and ceramic powders requiring ultra-fine particle size and high purity.
Ideal for high-end automotive coatings, industrial paints, and functional coatings where exceptional color consistency, gloss, and dispersion quality are required.
Used for producing high-quality digital inks, ceramic inks, and conductive inks, ensuring stable dispersion and precise particle size control.
Employed in wet grinding of pharmaceutical active ingredients and bio-materials where ultra-fine particle size and zero contamination are critical.
Applied in production of high-performance pesticide suspensions and crop protection formulations requiring stable nano-scale dispersion.
Used for grinding electronic pastes, dielectric materials, and advanced functional materials for semiconductor and display applications.

Micro-structure of delicate, uniform, dense ceramics of the Quartet — it has a gem-like hardness and density, making it the most premium medium in the full zirconia grinding series. Its excellent wear resistance and fracture toughness make it particularly suited for high-solid-phase, high-viscosity, high-hardness paste grinding and pure dispersion. It also delivers outstanding performance when paired with high-input-energy, high-shear sanding machines.
