What is it about?
This paper is about trying to understand how clays dissolve and go on to form certain zeolites. We tried to follow the process using infrared as this method is sensitive to environment. We learnt that the aluminium in solution does interact with the silicate species and changes with age. We also learnt that infrared can follow the formation of sodalite but LTA was harder.

Why is it important?
Using infrared as a means to follow crystallisation is a relatively simple method that can give a lot of information and so it is important to understand what this method can and can't do - as well as letting us know that in these systems the silicate is essentially monomeric though changes do happen with aluminate present.
Perspectives
I really liked how this paper came from a student project and linked in with an honours and PhD project. All the work really complemented each other and the paper shows that the infrared is quite powerful being able to look at both the solution and the solids.
