Low Abrasion Rate Zirconia Beads Ceramic Blasting Ball B40 for Magnesium Alloy Surface Finish
1. Description of Zirconia Beads Ceramic Blasting Ball
Zirconia Ceramic Beads is also called as ceramic beads,ceramic ball,it is one kind of ceramic blasting media.
It is made by fusion of zirconium sand in an electric furnace under high temperature,then made into different
micro beads through one special process.
Its main chemical composition is 60-66% ZrO2,while people are usually confused it with the one of zirconium
silicate beads which also contains 65% ZrO2.
Here we just make a simple comparation between the above two kinds of zirconia beads:
| Item | Ceramic Blasting Beads | Zirconium Silicate Beads |
| Chemical Index | ZrO2 60-66% SiO2 25-30% Al2O3 7-13% |
ZrO2 ≥65% SiO2 25-30% Others ≤1.0% |
| Processing Method | Melting | Sintering |
| Vickers Hardness | ≥700 HV | ≥900 HV |
| True Specific Gravity | ≥3.85 g/cm3 | ≥4.0g/cm3 |
| Bulk Density | ≥2.3g/cm3 | ≥2.5g/cm3 |
| Particle Size | B20-B205 etc | Φ0.1-10mm etc. |
| Usage | Blasting Media | Grinding Media |
Seen from the above chart,ceramic blasting beads has different processing method from the one
of zirconium silicate beads,then determines their different usuage: one in blasting application,
the other in grinding applications.
2. Main Particle Size of Zirconia Beads Ceramic Blasting Ball
| Particle Size | |
| B20: 0.600-0.850mm | B100: 0.125-0.180mm |
| B30: 0.425-0.600mm | B120: 0.063-0.125mm |
| B40: 0.250-0.425mm | B170: 0.045-0.090mm |
| B60: 0.125-0.250mm | B205: 0.000-0.063mm |
| B80: 0.180-0.250mm | B400: 0.030-0.063mm |
| Remark: Special specification can be customized | |
3. Product Features of Zirconia Beads Ceramic Blasting Ball
Lower beads consumption,which is 20-30 times compared with the one of glass beads;
No ferrous contamination compared with the steel shot;
Strong mechanical resistance and high toughness, but no damage to the blasting equipment;
Lower breakdown rate, consistent and high blasting efficiency;
Cleaner working environment and better operator’s visibility and no hidden dangers of silicosis.
5. Main Application of Zirconia Beads Ceramic Blasting Ball
Zirconia ceramic blasting beads has wide application as below:
In the civil field:
Ceramic blasting beads is widely used for surface cleaning of various metal products such as aluminium alloy,
titanium alloy and stainless steel parts;
Ceramic blasting beads is also used for finishing and surface pretreatment to remove the scale, rust, burrs etc..
Ceramic blasting beads is also widely used to clean various industrial tools such as glass processing, tire
manufacturing and plastic molding.
In the military field:
Ceramic blasting beads is usually used for surface strengthening of precision casting parts such as aircraft turbine
blades and various spring gear hydraulic parts to eliminate the internal stress.
