I am not able to get good literature and the physics behind how first these grains and grain boundaries arises out of no where when we make a pellet to study its dielectric properties and then how are they so important when studying its electrical properties.
Will love to hear its physics or provide me with good book which discuss these things and concept regarding the concept behind them!!
In ceramics, particle size determines the plasticity of the ceramic, but is also related to porosity and shrinkage. The smaller the particle size, the greater the vitrification with lower porosity.
It is important to note that the sintering temperature of the ceramic compound also determines the degree of vitrification of the compound. The higher the temperature, the greater the vitrification, and this most likely determines the dielectric properties of the ceramic.@anshul sharma
Grain size matter with respect to your specimen. the portion in nano could be as high as 68%. Phenomena in major related.
Grains and grain boundaries play a crucial role in determining the dielectric properties of ceramics. Here’s a breakdown of how they form and their significance:
