“…This research illustrated the capability to customize functional gradients and continuously arranged pore structures by modifying the morphology of the pore-forming agent and the tape casting process. Several studies have shown that the tape casting method can accurately control the thickness and composition of a single layer of materials and prepare gradient composites that can be designed and controlled; secondly, these studies have shown that cast molding is suitable for the rapid and large-scale production of gradient composites, providing a cost-effective and efficient manufacturing process with significant advantages [26][27][28][29][30].…”

Porous tungsten gradient materials with ordered gradient variations in pore size have significant application value in the field of vacuum electronic devices. This work combines tape casting and dealloying methods to achieve the integrated preparation of porous tungsten gradient materials with a wide range of controllable porosity. The study focused on the phase composition and microstructure evolution during the preparation of porous tungsten gradient materials. The results show that the tape casting process allows for the precise and controllable thickness of each layer of the porous tungsten materials and uniform composition structure, while the stepwise dealloying of Fe and Ti enables a wide range of controllable porosity for the porous tungsten gradient materials. PVB, after thermal decomposition, provides a carbon source for the in situ reaction to form W-Fe-C compounds, and the surface diffusion behavior of W-Fe-C compounds at high temperatures improves the stratification of the porous tungsten gradient materials. This work provides a design concept for the integrated preparation of porous metal gradient materials.

Zirconia ceramics, as a category of metal oxide ceramics, stand out due to their impressive physicochemical and mechanical properties. Recognized for being bioinert, these ceramics are non-toxic, exhibit excellent biocompatibility, and offer superior mechanical strength. Moreover, zirconia’s natural aesthetic qualities enable it to closely mimic the appearance of natural teeth, making it an optimal choice for dental restorations, such as crowns, bridges, and veneers. This review examines the complex relationship between zirconia’s microstructure, including aspects like grain size, porosity, and phase composition, and how these factors impact its translucency and mechanical durability. A specific focus is on the critical role of the tetragonal phase in zirconia, spotlighting its contribution to the material’s superior mechanical strength and esthetic qualities. The stabilization of this phase, primarily through the use of yttria, is discussed for its dual influence on enhancing both the material’s strength and esthetic properties. Challenges such as low-temperature degradation (LTD) and discoloration are highlighted, along with potential solutions like advanced surface modifications and novel manufacturing techniques. The potential of flash sintering and 3D printing to further improve zirconia’s properties is also explored.
