Material Characterization - XRD

X-ray diffractometers are not used to identify the physical properties of which of the following?

• Metals

• Polymeric materials

• Liquids

• Solids

This type of solid forms a regular repeating

three-dimensional structure called a crystal lattice. What type of solid is this?

• amorphous

• glass

• crystalline

• diamond

In amorphous solids, the atoms or molecules are held together in a completely random formation.

• True

• Flase

What is the example material of amorphous solid?

• Crystalline

• Poly-crystalline

• Glass

In XRD, We use known ....... measure ....... and calculate ....... spacing of the materials

• λ, θ, d

• θ, λ, d

• λ, d, θ

• θ, d, λ

What is the technique use in the X-ray characterization?

• Diffraction

• Reflection

• Emission

• Absorption

What is the purpose to do material characterization by XRD?

• To identify the crystal structure and atomic spacing

• To identify the crystal structure and surface morphology

• To identify the crystal structure and chemical compound

• To identify the crystal structure and band gap
