Bearing Silicon Nitride Si3n4 Zirconia Bead Zro2 Ceramic Balls for Ball Mill Machine
**Bearing Silicon Nitride Si3N4 Zirconia Bead ZrO2 Ceramic Balls for Ball Mill Machine**
**Product Overview:**
Our ceramic balls are made from high-purity zirconia (ZrO2) and silicon nitride (Si3N4), offering excellent mechanical properties and chemical resistance. These beads are ideal for use in ball mill machines, bearings, and other industrial applications where traditional materials may not perform well. They are designed to withstand extreme temperatures, resist corrosion, and provide long-lasting performance in harsh environments.
**Key Specifications:**
- **Model No.:** Si3N4 Zirconia Bead
- **Content:** ZrO2 (95%)
- **Application:** Bearings, Ball Mills, Grinding Media
- **Hardness:** 12.3 GPa
- **Working Temperature:** Up to 1500°C
- **Trademark:** Roshine
- **Transport Package:** 25kg per drum
- **Specification:** 0.1mm – 30mm
- **Origin:** Zibo, China
- **HS Code:** 6909120000
**Physical Parameters:**
These ceramic balls offer numerous advantages over metal or alloy alternatives. They operate effectively in a wide temperature range (-400°F to +500°F), exhibit chemical inertness against most corrosive substances, and have an extremely low coefficient of friction. PTFE balls are especially suitable for self-lubricating conditions such as ball bearings, while also being widely used in fluid handling industries for ball valves that come into contact with aggressive chemicals. Their design reduces maintenance costs and labor hours by minimizing the need for frequent replacements in corrosive settings.
**Detailed Specification:**
- **Material:** ZrO2 (95%)
- **Diameter:** 0.1mm – 55mm
- **Surface Finish:** Smooth, defect-free, with precision up to 0.01mm
- **Applications:** Used in pigment, paint, ceramic glaze, electronic materials, magnetic materials, cosmetics, and more
**Chemical Composition & Physical Properties:**
| Property | Value |
|----------|-------|
| ZrO2 | 95% |
| Compressive Strength | ≥2250 MPa |
| Hardness (Mohs) | ≥9 |
| Volume Density | ≥3.60 g/cm³ |
| Specific Density | ≥6.02 g/cm³ |
| Water Absorption | ≤0.01% |
