Composition

Much like our other ceramic balls, Zirconium Oxide has a simple chemical makeup. The formula is ZrO2 + Y203, (Zirconium and 2 Oxygen + 2 Yttrium and 3 Oxygen).

Properties

This formula gives our Zirconium Oxide bearings the following properties:

1. Density – 6
2. Friction Coefficient – 0.2
3. Specific Heat – 450
4. Coefficient of Linear Thermal Expansion – 10.5
5. Volume Resistivity - >10^11
6. Thermal Conductivity – 3.5
7. Young’s Modulus – 210
8. Relative Magnetic Permeability - <~1
9. Hardness – 87-91
10. Ultimate Compressive strength – 1750-2500
11. Service Temperature – 0/1350

Weaknesses

While this material has a lot of strengths that would make it work in various industries, Zirconium Oxide is not ideal for high-alkaline environments or hydrofluoric and sulfuric acids.

Uses

Our Zirconium Oxide bearings are commonly used in with material handling equipment, electronics, oil industry, food processing and agricultural, energy, and medical industry.

Global Precision Standard

To ensure that every batch of our balls meets our high standards, we put each batch through tests and examine them. This ensures that your order will be high-quality.
