Enother interesting information: specially for you.
Discussion
- What do you think about this? see, .
- @ljaureguiv haha, just what I was thinking!
- Interesting. What were the ratios used of Er and Pr? What causes the spontaneous ignition?
- Asome my element is the coolest in my class!
- Sorry for the late response. The ratio Er-Pr used was 73-27. This normally should not ignite (or oxidize rapidly). This little experiment was done after an accident when opening a jar. The cause is the presence of sub-micron particles. Like magnesium dust, for example, it oxidizes fast as the total surface area is very large. This experiment is another proof that you don´t always get what you ask for as we ordered a specific particle size (150microns). But the chinese supplier seemed cheap...
