💖Zirconia ball use: especially suitable for vertical stirring mill, horizontal rolling ball mill, vibration mill and all kinds of high line speed rod pin sand mill; Wet and dry ultrafine dispersion and grinding of all kinds of slurry and powder that are required to refuse cross-contamination.
💖Application areas are as follows: A. wear and corrosion resistant products: coatings, textiles, pigments, printing and dyeing; B. High strength, high toughness products: magnetic materials, piezoelectric ceramics, dielectric ceramics; C. Prevention of pollution: medicine, food, cosmetics; D. Ceramics: electronic ceramics, refractory ceramics, structural ceramics
💖Zirconia ball features: high strength and toughness at room temperature, high density, good wear resistance, high temperature corrosion resistance, high stiffness, non-magnetic permeability, electrical insulation, thermal expansion coefficient close to steel and other advantages. When the zirconia ceramic ball is at 600℃, the strength and hardness are almost unchanged. Using yttrium oxide as stabilizer, it is made by special molding process and high temperature roasting and phase fixing process.
