“…X Y Zhai et.al [23] and Q Jin et.al [24] have achieved indium tin oxide (ITO) and BaTiO3 fine-grained ceramics with high relative density under conventional sintering conditions, respectively. They considered that this method is similar to the self-assembly process of colloidal crystal, and named this way as a self-assembly sintering method [24]. What is more, researchers have pointed out the requirements met by the two sizes of powders and their reasonable ratios by the calculations of close packing model, and gave the general conditions for this method [22][23][24].…”

“…Studies have shown that using the intrinsic properties of powders, such as morphology, size and so on, through the combination of powders with different sizes then co-sintering, the contradiction between densification and grain growth can be balanced [18][19][20][21][22][23][24]. Consequently, the fine-grained ceramics with high relative density can be obtained by sintering under conventional conditions [20][21][22][23][24]. For example, J W Oh et.al [21] used the Fe powders with sizes 3 μm and 100 nm to co-sintering.…”

“…H Y Xu et.al [22] utilized the same way to synthesize the Al2O3 dense fine-grained ceramics by 3 μm and 220 nm Al2O3 powders, whose relative density is 92.2% and grain size is 250 nm. The researchers found that when combining two sizes of powders, the key point is that the sizes must meet the requirements of the close-packed model, because it can maximize the space utilization [23][24][25][26][27].

In this paper, from the perspective of thermodynamics and kinetics, we have studied the mechanism of balancing the densification and grain growth via co-sintering the micron and nano powders, also known as self-assembly sintering. In the experiment, the 200 nm and 80 nm BaTiO 3 spherical powders were used as models for combination and co-sintering. In terms of thermodynamics, the contact angle method is applied to determine the free energy of the binary particle size system. The surface free energy of 200 nm and 80 nm BaTiO 3 powders are 51.66 J/mol and 203.47 J/mol, respectively. When the powder ratio is 1:1, the surface free energy of the binary particle size system is 127.56 J/mol, which is the reason for the balance between densification and grain growth. In terms of kinetics, the Arrhenius equation was utilized to calculate the apparent activation energy ( Q ) of the binary particle size system. The results show that the value of Q is 360 kJ/mol at 1000 °C. The fine-grained ceramics with high relative density obtained by this sintering method at a low sintering temperature (1000 °C) can be explained by the relative low value of Q.
