Materials - Introduction
10 important questions on Materials - Introduction
What happens if you select a wrong technique?
What is a mineralogical way of looking at things?
What is a chemical/elemental way of looking at things?
- Look at the elements themselves
- For example the structure of sand
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
How do you deal with alterations/prone materials?
- Correct for them
- Pick the right samples
What metals are not resistant to alteration?
- Glass
- Metal
How can we identify with what element we are dealing?
Quantitative research elements
In what weight percentage are elements expressed?
Trace elements: ppm
What is the basis of research by the means of electromagnetic radiation?
- All techniques are based on electromagnetic radiation = the light around us
- This energy is called the incident energy = start energy.
- That start energy will react with our sample.
- Based on the energy, the reaction will be different (transmitted, resorbed or reflected)
How can we determine what elements are present by the means of electromagnetic radiation?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
