Figure 4

The phase diagram of Nan/Na12-LSX zeolite showing the values of (a) (1/T1T )metal, (b) normalized N(EF) and (c) NMR spectrum intensity for ZC and SC as a function of Na loading level n. The colour gradient divides the insulating and metallic regions as experimentally observed from the resistivity and optical conductivity measurements.
