Specifications of 94.7% ZrO2 5.2% Y2O3 Yttrium Stabilized Zirconia Ceramic Tetragonal Phase, Used for Oxygen Sensors and Fine Ceramics

This material combines 94.7% zirconium dioxide (ZrO2) and 5.2% yttrium oxide (Y2O3). The yttrium acts as a stabilizer. It ensures the zirconia maintains a tetragonal crystal structure at room temperature. This phase offers high mechanical strength and thermal stability. The material suits applications requiring durability under extreme conditions.

The stabilized tetragonal phase resists phase transformation under stress. This prevents cracking during rapid temperature changes. The material handles temperatures up to 1,400°C. It remains stable in oxidizing and reducing atmospheres. This makes it ideal for oxygen sensors. The sensors measure oxygen levels in automotive exhaust systems and industrial processes.

The ceramic has excellent oxygen ion conductivity. This property is critical for sensor accuracy. It allows efficient ion movement at high temperatures. The material also resists corrosion from harsh chemicals. It performs well in acidic or alkaline environments. This extends the lifespan of components made from it.

Key specifications include a density of 6.05 g/cm³. The Vickers hardness exceeds 1,200 HV. The fracture toughness is around 8 MPa·m¹/². These values indicate strong resistance to wear and impact. The thermal expansion coefficient is 10.5×10⁻⁶/°C (20–1,000°C). This minimizes thermal stress during heating or cooling cycles.

The material’s low thermal conductivity (2.5 W/m·K) aids insulation in high-temperature setups. Its flexural strength reaches 1,000 MPa. This supports use in structural parts under heavy loads. The grain size is controlled below 0.5 micrometers. Fine grains enhance mechanical properties and surface smoothness.

Applications extend beyond oxygen sensors. The ceramic is used in precision components for aerospace and medical devices. It serves as crucibles for molten metal processing. Its wear resistance suits cutting tools and grinding media. Electrical insulation properties make it viable in electronic substrates.

Processing methods include dry pressing and sintering. Tight controls ensure consistent quality. Final products undergo grinding and polishing for precise dimensions. Custom shapes and sizes are achievable. The material meets industry standards for high-performance ceramics.

Testing confirms compliance with thermal and mechanical requirements. Batch consistency is prioritized for industrial users. The ceramic is packaged to prevent damage during shipping. Technical support is available for application-specific queries.

5 FAQs of 94.7% ZrO2 5.2% Y2O3 Yttrium Stabilized Zirconia Ceramic Tetragonal Phase, Used for Oxygen Sensors and Fine Ceramics

What is 94.7% ZrO2 5.2% Y2O3 yttrium-stabilized zirconia ceramic?
This material is a ceramic compound containing 94.7% zirconium dioxide (ZrO2) and 5.2% yttrium oxide (Y2O3). The yttrium stabilizes the zirconia in its tetragonal crystal phase. This structure improves strength and thermal resistance. It is ideal for high-stress environments like oxygen sensors and precision ceramics.

Why is yttrium added to zirconia ceramics?
Yttrium oxide stops the zirconia from changing its crystal structure under heat or stress. Pure zirconia can crack when temperatures shift. The yttrium keeps the tetragonal phase stable. This prevents cracks and makes the material last longer in tough conditions.

What applications use this zirconia ceramic?
It is mainly used in oxygen sensors for cars and industrial machines. These sensors measure oxygen levels in exhaust systems. The ceramic’s stability ensures accurate readings. It is also used in fine ceramics for medical tools, cutting blades, and industrial parts needing durability.

What benefits does this material offer?
The ceramic resists high temperatures, wear, and corrosion. It stays strong under mechanical stress. Its low thermal conductivity reduces heat transfer. These traits make it reliable in harsh settings. Its stability ensures consistent performance over time.

How should this ceramic be handled during use?
Avoid exposing it to sudden temperature changes. This prevents thermal shock. Keep it clean to maintain performance. Follow manufacturer guidelines for installation. Use proper tools to prevent physical damage. Store it in a dry place to avoid moisture absorption before use.
