Application Scientist Interview Questions and Answers

Various characterization techniques can be used for solid particles to analyze their properties.

• Particle size analysis using techniques like laser diffraction or microscopy

• Surface area measurement using BET analysis

• Chemical composition analysis using techniques like X-ray diffraction or spectroscopy

• Morphology analysis using techniques like electron microscopy

• Porosity analysis using techniques like mercury intrusion porosimetry

Physical properties of solid materials include density, hardness, melting point, and conductivity.

• Density: mass per unit volume of a material (e.g. lead is denser than aluminum)

• Hardness: resistance of a material to deformation or scratching (e.g. diamond is harder than graphite)

• Melting point: temperature at which a solid material changes to a liquid state (e.g. iron melts at 1538°C)

• Conductivity: ability of a material to conduct heat or electricity (e.g. copper is a good condu...read more
