  • 3 Fundamentals of Crystallography

  • 1. Describe the difference in atomic/molecular structure between crystalline and noncrystalline materials.
    2. Given three direction index integers, sketch the direction corresponding to these indices within a unit cell.
    3. Specify the Miller indices for a plane that has been drawn within a unit cell.
    4. Distinguish between single crystals and polycrystalline materials.
    5. Define isotrophy and anisotrophy with respect to material properties.

  • 3.1 Introduction

  • What is discussed in chapter 3?
    In chapter 3 is the structure of materials discussed. There will be a focus on crystalline structures.
  • 3.2 Fundamental Concepts

  • What is a crystalline material?
    A crystalline material is a material in which the atoms are arranged in a periodic manner over large atomic distances.
  • What is a crystal structure?
    A crystal structure is the way in which particles are spatially arranged.
  • What is the atomic hard-sphere model?
    In the atomic hard-sphere model, atoms are represented as solid spheres. In this model nearest-neighbor atoms touch each other.
  • What does the term lattice mean in context of crystal structures?
    Here lattice means a three-dimensional array of points coinciding with atom position.
  • 3.3 Unit Cells

  • Why is it convenient to use unit cells?
    Since atoms occur in a repetitive array in crystal structures, it is possible to subdivide the structure, resulting in a parallelepiped.
  • 3.4 Crystal Systems

  • What are the seven crystal systems?
    1. Cubic
    2. Hexagonal
    3. Tetragonal
    4. Rhomboheral (trigonal)
    5. Orthorhombic
    6. Monoclinic
    7. Triclinic
  • What are the axial relationships and interaxial angles of the Cubic crystal system?
    Axial relationship: a = b = c
    Interaxial angles: α = β = γ = 90°
  • What are the axial relationships and interaxial angles of the Hexagonal crystal system?
    Axial relationship: a = b ≠ c
    Interaxial angles: α = β = 90° ,γ = 120°
  • What are the axial relationships and interaxial angles of the Tetragonal crystal system?
    Axial relationship: a = b ≠ c
    Interaxial angles: α = β = γ = 90°
  • What are the axial relationships and interaxial angles of the Rhombohedral (Trigonal) crystal system?
    Axial relationship: a = b = c
    Interaxial angles: α = β = γ ≠ 90°
  • What are the axial relationships and interaxial angles of the Orthohombic crystal system?
    Axial relationship: a ≠ b ≠ c
    Interaxial angles: α = β = γ = 90°
  • What are the axial relationships and interaxial angles of the Monoclinic crystal system?
    Axial relationship: a ≠ b ≠ c
    Interaxial angles: α = γ = 90° ≠ β
  • What are the axial relationships and interaxial angles of the Triclinic crystal system?
    Axial relationship: a ≠ b ≠ c
    Interaxial angles: α ≠ β ≠ γ ≠ 90°
