Crustal abundance of chemical elementsΒΆ

Here I show the crustal abundance of the different naturally occurring elements, as taken from the Handbook of Chemistry and Physics. Other elements such as selenium or tellurium, key in thin film photovoltaics, are less abundant than rare earths.

Something to note is that rare earths are not really that scarce: it is a combination of lack of concentrated ores what makes it so hard to extract.

The topic of critical materials is one of my favorite areas in sustainability. Some interesting resources are the following reports:
