Phase equilibria were studied for the system Na 2 SiO :r Li 2 SiO 3 . The 2 end‐member metasilicates show limited mutual solid solubility with the (Na 2‐χ Li χ )SiO 3 solid solutions being particularly extensive at solidus temperatures (0 x 1.06). Ordering of the latter solid solution occurs at the NaLiSiO ;) composition with a supercellx = 6a subcell During cooling of the solid solutions, metastable phase transformations occur; a twinned monoclinic metastable phase, low (Na, Li) 2 SiO 3 , has been characterized.
