Highly polished YSZ (Yttrium stabilized ZrO2) zirconium oxide jars has the performance of high wear resistance. Its hardness is 60 times the hardness of ordinary steel, highly wear-resistant and resistant to acid and solvents. The grinding jars are extensively applied on in the fields of Paint, Ink,Coating, Geology, Metallurgy, Electronics, Construction Material, Ceramics, Chemical Engineering, Light Industry, Medicine, Environmental Protection and so on. Each jar set includes grinding jar, jar lid, rubber sealing gasket and different sizes of mixed zirconium oxide grinding balls. ItemParameterMaterial5wt%Y2O3+95wt%Zro2Crystal structureHigh temperature hexagonal ,low temperature tetragonalBending strength (Mpa) 20C200-300Density (g/cm3)6.04Fracture toughness KIC 20C (Mpa m1/2)2.3Hardness (HV) 20C1000Thermal conductivity W/mk27Specific heat (J/g/k)0.45Thermal expansion coefficient *106/C 20C-100C10Melting point2715℃Temperature range0~2300℃Applicable environmentIngot furnace and corrosive gas furnaceTechnical DataJar Volume Volume OD (mm) ID (mm) Height (mm) 50ml 55 38 67 100ml 65 50 75 250ml 92 74 88 500ml 100 84 118 1000ml 128 108 150 1.5L 132 112 175 2.0L 158 138 162 3.0L 158 138 220 4.0L 205 175 231 5.0L 192 170 254 Choice of Grinding Jars&Grinding Ball In order to prevent excessive abrasion, the hardness of the grinding jars used and of the grinding balls must be higher than that of the material used. Normally, grinding jars and grinding balls of the same material should be chosen. Features1. High specific gravity, high efficiency2. Highly wear resistant to acid and solvents3. High cost-effective, low wear and long lifetime4. Highly polished, smooth, easy to clean, low abrasion to the equipment5. High mechanical strength, good toughness, impact resistance, no broken beads6. Mainly used for lab planetary ball mill machines
