керамический шарик - чистый оксид циркония Y2O3, шлифовальные фу

ceramicball: is made of good raw material and we adopt advanced technology.Its applicable for lab equipment,sand mill,attrition ball mill,roller ball mill,which grind and disperse electronic material,ceremic powder,battery raw material, nonmetal mine, painting, pesticide, foodstuff, medicine. Compared with traditional grinding mediums,zirconia ball(Y-TZP grinding medium)has property of high density,high hardness,high hardness ,better grinding efficiency.High wear-resistant zirconia can prevent material from contamination.It can also avoid chemical erosion which effect the grinding medium life.Ultra-fine zirconia raw material guarantee compact microstructure, pearlescent colour and roundness stand for the best grinding medium. Its suitable for grinding material that requires no pollution. propertyunitparameterContentwt%94.6% ZrO2 5.2%Y2O3Packing densitykg/L3.5 (5mm)Densityg/cm36.00Hardness(HV)GPa>12Elastic modulisGPa200Thermal conductivityW/m.K3thermal Expansion coefficient10×10-6/°C (20 to 400)9.6Pressing intensityKN≥25(5mm)Fracture tenacityMPam½8Grain sizeµm≤0.5
