Zirocnia Ceramics:
In general, the higher the dispersion of the material, the higher the surface energy. Therefore, it has a strong force to promote migration and diffusion, which is conducive to sintering. At the same time, in the process of full pulverization, the defects inside and on the surface of the particles increase, effectively improving The mobility of the particles. Whether in solid or liquid sintering, fine particles increase the sintering rate by increasing the driving force of sintering, shortening the atomic diffusion distance and increasing the solubility of the particles in the liquid phase. When the agglomeration of the original powder particles is serious and the compact packing property is poor, and the pressure gradient is distributed when the green body is pressed and the admixture is not mixed with the powder, the density and composition of the various parts of the green body are uneven. The green body thus produces uneven densification upon sintering. Usually, the addition of an admixture will cause the grain boundary movement of the material during sintering to suppress grain growth, but in some cases, the result is just the opposite. For example, in solid phase sintering, a small amount of additives (also known as sintering aids) can form a solid solution with the main crystalline phase to promote the increase of defects; in liquid phase sintering, additives can change the properties of the liquid phase (such as viscosity, composition, etc.) To promote the role of sintering.
