Ceramic Grinding Media-Two Kinds Of Zirconia Ceramic Bead
1.With the more demand for the Ceramic grind media, especially for zirconia ceramic ball, this kind becomes a favorite in the grinding material field. With superior quality and performance, Chemshun zirconia ceramic beads fulfill the requirement of many industries such as battery,materials, magnetic materials,silicon oxide,kaolin,cacluim carbonate,titanium dioxide,coating,pigment,dye,ink,papermaking,blasting,mining, etc,
2.Here we introduce two main kinds :Yttria stabilized zirconia bead and Ceria stabilized zirconia bead.
1) Yttria stabilized zirconia beads is shorten as Y-TZP zirconia ceramic balls, it has 30-50 times higher wear-resistance as glass beads,5 times higher as zirconium silicate beads and 6-8 times higher as Al2O3 beads. Because of the high density and excellent grinding efficiency of Y-TZP beads, they greatly apply to grinding and dispersing high viscosity materials.
Its technical specificatio and its appearance are shown below:
| Item | Value |
| Oxide Proportion | ZrO2: 94.8%±0.2%; Y2O3: 5.2%±0.2% |
| Specific Density | >=6.00g/cm3 |
| Bulk Density | >=3.7g/cm3 |
| Vickers Hardness | >1200HV |
| Compressive Strength | >2.0KN(Φ2mm) |
| Self Consumption | <0.5ppm/h |
| Roundness | >=0.96 (Xmin/Xmax) |
| Surface Glossiness | Smooth |
| Color | White |
| Diameter range | 0.1mm-55mm. It can be customized. |
| Application | Paint and varnish industry, ceramic industry, pest management, beauty culture, pharmacy, battery material etc. |
2) Ceria stabilized zirconia beads can be called as Ce-TZP zirconia ceramic balls,with the properties of never aging and never broken, It has a very long service life, and its abrasion is the smallest of all zirconia ball with excellent wear-resistance performance. It widely used in grinding of factories of inks, paper, paints, metal and non-metallic mineral etc.
Its technical specification and its appearance are shown below:
| Item | Value |
| Oxide Proportion | ZrO2:83-87%, CeO2: 9-13%, Others:<2.0% |
| Specific Density | >=6.10g/cm3 |
| Bulk Density | >=3.75g/cm3 |
| Vickers Hardness | >1150HV |
| Compressive Strength | >1.5KN(Φ2mm) |
| Self Consumption | <0.8ppm/h |
| Roundness | >=0.97 (Xmin/Xmax) |
| Surface Glossiness | Smooth |
| Color | Yellow/Brown |
| Diameter range | 0.3mm-30mm. It can be customized. |
| Application | Inks,paper,paints,metal and non-metallic mineral |
3) When we make a comparison for Y-TZP abd Ce-TZP ceramic balls, they have some different aspects as following:
In term of the applicable industry, the scope of the white ball(Y-TZP) is more larger than the yellow ball(Ce-TZP).
In term of hardness, the Y-TZP beads is better than the Ce-TZP beads,
In term of density, the Y-TZP beads is higher than the Ce-TZP beads
In term of self consumption, the Y-TZP beads is better than the Ce-TZP beads
In term of the price , the Y-TZP beads is higher than the Ce-TZP beads
In term of the grind mill, the Ce-TZP beads is used only in sand mill, while the white ball(Y-TZP) can be used in sand mill and ball mill.
Also they have something in common,they are can be used in the same industry,and popular in the market.
