SSF PLASTICS Maintenance Technician Interview Questions and Answers

Q1. XRD Test Parameter
Ans. 
XRD (X-ray Diffraction) test parameters are crucial for analyzing crystalline materials and determining their structure.
• XRD measures the angles and intensities of X-rays scattered by a material.

• Key parameters include 2θ (scattering angle), wavelength, and sample preparation.

• Example: A smaller 2θ value indicates larger interplanar spacing in crystals.

• The choice of X-ray source (Cu Kα, Mo Kα) affects resolution and sampl...read more
