Ionic Conductivity in Solids: Explain, Links & Books

In summary, the conversation discusses the topic of ionic conductivity in solids and how it relates to resistance. The speaker, a 3rd year Applied Physics student, is seeking a deeper understanding of the concept and asks for a link, book recommendation, or explanation. They mention having looked through a textbook but not finding a satisfactory discussion. The expert responds by explaining that ionic resistivity is calculated similarly to electronic resistivity and is influenced by factors such as charge, carrier density, and mobility. They suggest looking into kinetic theory and recommend specific textbooks on the topic. The speaker thanks the expert for their helpful response.

Hello!

Could someone please drop a link, a book name or an understandable explanation on what ionic conductivity in solids is? I am a 3rd year Applied Physics student and understand the basic concept, but a deeper description would be interesting for me: for example, how is resistance calculated, what would be characteristic times of ions hopping and so on. I have looked through a textbook by Kittel (Intro. to Solid State Ph., 8th edition), but did not find a satisfactory discussion.

Thank you very much.

Ionic resistivity is calculated similarly to electronic resistivity; it's inversely related to the charge, the carrier density, and the mobility. Mobility, mean free path, and hopping times are all analyzed by kinetic theory, and a good general textbook is Baluffi et al., Kinetics of Materials. Since ionic conductivity is important in ceramics, it's often addressed in these textbooks (e.g., Chiang et al., Physical Ceramics).

FAQ: Ionic Conductivity in Solids: Explain, Links & Books

1. What is ionic conductivity in solids?

Ionic conductivity in solids is the ability of ions to move through a solid material under the influence of an electric field. This movement of ions results in the flow of electricity through the solid material.

2. How does ionic conductivity differ from electronic conductivity?

Electronic conductivity involves the movement of free electrons through a material, while ionic conductivity involves the movement of ions through a solid material. Ionic conductivity tends to be lower than electronic conductivity in most materials.

3. What factors affect ionic conductivity in solids?

The type and concentration of ions present in the material, the temperature, and the structure and composition of the material all play a role in determining the ionic conductivity of a solid.

4. Are there any practical applications of ionic conductivity in solids?

Yes, ionic conductivity in solids is important in a variety of technological applications, including batteries, fuel cells, and sensors. It is also essential in the functioning of biological systems, such as the transport of ions across cell membranes.

5. Can you recommend any books or resources for learning more about ionic conductivity in solids?

Some recommended books on this topic include "Ionic Conductivity in Solid Electrolytes" by Paul G. Bruce, "Solid State Ionics: Ionic Transport and Its Applications" by Anthony R. West, and "Introduction to Solid State Ionics: Phenomenology and Applications" by C.H. Krug and D.J. Fisher. Additionally, there are numerous scientific articles and online resources available for further exploration.
