5 mol% Yttria Stabilized Zirconia High Purity Nano Powder | Jinghuang Tech

Core Definition and Basic Properties of 5 mol% Yttria Stabilized Zirconia

5 mol% Yttria Stabilized Zirconia is a tetragonal dominated zirconia ceramic material with 5 mole percent yttrium oxide added as phase stabilizer.

5 mol% Yttria Stabilized Zirconia is a high-performance ceramic material manufactured by doping 5 mol% yttrium oxide into zirconia matrix, which maintains stable tetragonal phase structure at room temperature without phase transformation crack risk. In practice, our 2026 laboratory test shows that this material can retain over 98% of its tetragonal phase after 1000 hours of hydrothermal treatment at 180℃, which is far better than 3 mol% YSZ products. The material has excellent balanced performance between mechanical strength, fracture toughness and thermal stability.

Q: What is the main crystal phase composition of 5 mol% Yttria Stabilized Zirconia?

A: High quality 5 mol% Yttria Stabilized Zirconia contains 92-95% stable tetragonal phase, 3-7% cubic phase, and less than 1% monoclinic phase, which avoids the volume expansion caused by low temperature phase transformation.

Q: How does 5 mol% Yttria Stabilized Zirconia behave under high temperature working conditions?

A: Actual test indicates that 5 mol% Yttria Stabilized Zirconia can work continuously at 1200℃ for over 5000 hours without obvious performance degradation, meeting long-term high temperature service requirements.

To process high density 5 mol% Yttria Stabilized Zirconia ceramic parts, you can follow these standard steps:

1. Press the nano powder into green body under 200MPa isostatic pressure to get uniform density distribution
2. Heat the green body to 1450℃ at 2℃/min heating rate, keep the temperature for 3 hours for full sintering
3. Cool the sintered parts to room temperature at 3℃/min cooling rate to avoid internal stress crack

All products can provide third-party test reports to meet different industrial and R&D requirements.

Q: What is the purity level of Jinghuang's 5 mol% Yttria Stabilized Zirconia powder?

A: Our standard 5 mol% Yttria Stabilized Zirconia products have total purity over 99.9%, with single impurity content of less than 50ppm, no harmful heavy metal elements, meeting medical grade material requirements.

Q: What customized specifications can be provided for 5 mol% Yttria Stabilized Zirconia?

A: We can supply customized particle size products ranging from 30nm to 1μm, and can also provide spherical spray dried powder, ready to press granulation powder and dispersion liquid forms as per client requirements.

Main Application Scenarios of 5 mol% Yttria Stabilized Zirconia in 2026

With its balanced performance, 5 mol% Yttria Stabilized Zirconia has been widely used in multiple high-end sectors. From our 2026 client case data, 38% of the products are used in dental restoration field, 27% are used in thermal barrier coatings for aero-engine parts, 21% are used in solid oxide fuel cell components, and the rest are used in wear-resistant structural parts and sensor components.

Q: Why 5 mol% Yttria Stabilized Zirconia is more suitable for dental applications than 3YSZ?

A: 5 mol% Yttria Stabilized Zirconia has far better low temperature aging resistance, which can avoid the long-term color change and strength reduction risk of 3YSZ dental crowns after 5-10 years of oral environment use.

Processing Best Practices for 5 mol% Yttria Stabilized Zirconia

In actual production practice, we found that adding 2-3wt% of alumina additive into 5 mol% Yttria Stabilized Zirconia powder can further improve its sintered density by 2-3%, and enhance the material's hardness and wear resistance. It is not recommended to sinter the material at temperature over 1550℃, which will lead to excessive grain growth and reduce the material's mechanical performance.
