**ZrO₂ (ZrO) Ceramic Massage Block**
ZrO₂ (zirconia) is a high-performance ceramic material that is highly popular in the field of precision measurements such as ceramic mass blocks due to its unique physical and chemical properties. The following is a detailed introduction to the zirconia ceramic mass:
**1. Material properties of ZrO₂**
- **Ultra-high hardness and wear resistance**
The Vickers hardness of zirconia can reach **1200-1400 HV**, close to tungsten carbide, far higher than steel (about 200-300 HV), with almost no wear on the surface and maintaining accuracy for a long time (micron level).
- **Extremely low thermal expansion coefficient**
The thermal expansion coefficient is **10-11×10⁻⁶/°C** (compared with steel), and has excellent dimensional stability under temperature fluctuations, making it suitable for constant temperature laboratories or industrial environments with large temperature differences.
- **High fracture toughness**
By adding stabilizers (such as Y₂O₃), zirconia can achieve phase transition toughness, with fracture toughness up to **6-12 MPa·m¹/²**, and crack resistance is better than ordinary ceramics (such as alumina).
- **Corrosion resistance and bioinergicity**
Resistant to acid and alkali, salt spray and organic solvent corrosion, and non-toxic and non-magnetic. It is suitable for clean environments such as medical and semiconductors.
- **Lightweight and low density**
The density is approximately **6.0 g/cm³** (only 3/4 of steel), reducing the operating burden.
**2. Core advantages of zirconia ceramic mass block**
| ** Features** | ** Gain to mass performance** |
|----------------|---------------------------------------------|
| **Abrasion resistance** | Reduce scratches when calibration tools (such as micrometers) come into contact with measuring blocks and extend life. |
| **Thermal stability** | The error is controllable under temperature fluctuations, suitable for high-precision CMM (coordinate measuring machine) calibration. |
| **Chemical Inert** | Keep the size undeformed in corrosive environments (such as plating workshops, chemical plants). |
| **Non-magnetic** | Avoid interference with magnetically sensitive equipment (such as MRI instruments, electronic components). |
**3. Application scenarios**
- **Semiconductor manufacturing**: wafer alignment, lithography machine platform calibration (nano-level accuracy required).
- **Precision mold testing**: Size verification of injection molds and stamping molds.
- **Medical Equipment**: High-precision measurement in surgical instruments and implant processing.
- **Extreme Environment**: Monitoring of workpiece dimensions in high-temperature furnaces, and anti-corrosion detection of marine equipment.
