Electric field sintering zirconia ceramics

---

Electric field sintering zirconia ceramics is an advanced preparation technology that utilizes direct current or alternating current electric fields to achieve rapid densification of ceramics at temperatures lower than traditional sintering temperatures. This technology can effectively suppress grain growth, improve material density and mechanical properties.

Addressing core user needs
-Shorten R&D and production cycles: achieve rapid sintering and significantly reduce process time.
-Enhance product performance: Obtain ceramic components with higher density and better mechanical properties.
-Reduce energy consumption costs: Low temperature rapid sintering significantly reduces energy consumption.
-Realize complex structure forming: support customized manufacturing of high-precision and complex shaped ceramic parts.

Advantages and User Value
Electric field sintering technology (such as flash sintering FS and field assisted sintering FAST) has demonstrated disruptive advantages in the preparation of zirconia ceramics, bringing significant value to the high-end manufacturing field.
Low temperature rapid densification: The sintering temperature can be reduced to 850-1025 ℃, the time can be shortened to seconds to minutes, and the energy consumption is only less than 10% of traditional processes.
Excellent microstructure control: effectively suppresses abnormal grain growth, obtains fine and uniform microstructure, and improves material strength and toughness.
High density and low deformation: The density is close to the theoretical density, and the sintering deformation rate is extremely low, meeting high-precision dimensional requirements.
Green and low-carbon manufacturing: low energy consumption, low carbon emissions, in line with sustainable development and green manufacturing trends.

Customer Application Cases
A well-known medical device enterprise needs to develop a new generation of high-strength and toughness all ceramic dental crowns. The traditional sintering process has problems such as coarse grains, poor edge fit, and high fracture rate. We provide them with a customized scheme for electric field sintering of zirconia crowns: 3Y ZrO ₂ nano powder is used, through dry pressing+isostatic pressing composite molding, and flash firing technology is used to carry out 30 second rapid densification at 950 ℃.
The final product performance has significantly improved: the three-point bending strength reaches over 1200 MPa, the Vickers hardness is 12.5 GPa, the grain size is uniform (<0.5 μ m), the edge fit is controlled within ± 10 μ m, and the clinical fracture rate has decreased by 60%. The customer has incorporated this process into their high-end dental restoration product line standard process.
