Low Abrasion Ceramic Blasting Media B100 45 - 90μM For 3C Cellphone Rear Cover Surface Finish
Low Abrasion Ceramic Blasting Media B170 45-90μm for 3C Cellphone Rear Cover Surface Finish
1. Product Description of Ceramic Bead
Ceramic Bead contains 62-66% ZrO2,it is also called as zirconia bead. While different from the 65 zirconia
grinding beads(Zirconium Silicate Beads),ceramic bead is one popular blasting media with high price/
performance ratio.
2. The comparation between Ceramic Bead Blasting Media and Zirconium Silicate Beads
People usually consider ceramic bead blasting media is the same abrasive as the one of 65 zirconia grinding
beads,while they are different in chemical index and actual appliactions as below:
| Item |
Ceramic Bead Blasting Media |
Zirconium Silicate Beads (65 Zirconia Grinding Beads) |
| Chemical Index | ZrO2 60-66% SiO2 25-30% Al2O3 7-13% |
ZrO2 ≥65% SiO2 25-30% Others ≤1.0% |
| Vickers Hardness | ≥700 HV | ≥900HV |
| True Specific Gravity | ≥3.85 g/cm3 | ≥4.0g/cm3 |
| Bulk Density | ≥2.3g/cm3 | ≥2.5g/cm3 |
| Particle Size | 0.04-0.85mm | Φ0.1-10mm |
| Usage | Blasting Media | Grinding Media |
3. Application Comparation between Ceramic Bead Blasting Media and Zirconium Silciate Beads
| Product Name | Ceramic Bead Blasting Media | Zirconium Silicate Beads |
| Usage | Blasting Media | Grinding Media |
| Application |
1. Surface finish for 3C products, 2. Surface finish for medical instruments,golf clubs; |
ultra-fine grinding of calcium carbonate, kaolin, titanium dioxide, paints, paints, inks, etc. |

5. How to calculate the media blasting cost?
| Media Blasting Cost | ||
| Media Name | Cycles | %Breakdown |
| Glass Beads | 9-12 | 10% |
| Ceramic Beads | 70-90 | 1.20% |
| Steel shot | 80-100 | 1% |
| Media Cost Per Hour=Hourly Delivery Rate*%Breakdown*cost per Lb. | ||
| Media Cost to Blast a Part=Media Cost Per Hour*Part cycle time(% of Hour) | ||
Media blasting cost is one important index to choose one right blasting media, you will
find the answer from the above chart.
6. Which kind of blasting media can be replaced by Ceramic Beads?
Ceramic beads can replace glass beads where one cleaner work condition is required or replce steel shot
where ferrous contamination is not allowed.
Ceramic beads has medium density,which can make up the lower and upper limit of steel shot and glass
beads in blasting effect.
Compared with glass beads,ceramic beads will achieve more shinny visual effect and more consistent
blasting effect.
Compared with steel shot,ceramic beads will also provide one shinny visual effect , no discoloration.
