Solid State Chemistry Overview

Definition

• Solid state chemistry is the study of the synthesis, structure, and properties of solid phase materials, especially crystals.

Key Concepts

• Crystallography: Study of crystal structures and their properties; involves X-ray diffraction techniques.
• Lattice Structure: Arrangement of atoms in a crystalline solid; includes unit cells.
• Types of Lattices:
  • Simple cubic
  • Body-centered cubic (BCC)
  • Face-centered cubic (FCC)
  • Hexagonal close-packed (HCP)

Solid State Reactions

• Types:
  • Solid-state synthesis
  • Diffusion mechanisms
• Factors Affecting Reactions: Temperature, pressure, and chemical composition.

Characteristics of Solids

• Electrical Properties:
  • Conductors, insulators, and semiconductors based on electron mobility.
