I was told, by whom I have no idea, that the fluxing power of the alkalis has to do with ion diameter and the ability of the ions to enter and spread the tetrahedral bonds of silica. My copy of Handbook of Chemistry and Physics doesn't have data on ion sizes, but it is almost as old as I am. Do recent editions have such info? Which is larger among sodium, potassium and lithium? Does it make sense with expansion and what we know about fluxing power?
