A new compound, Na(6)Si(8)O(19), is shown to be a thermodynamically stable phase in the Na(2)O-SiO(2) system at 1 atmosphere. The new compound melts incongruently to SiO(2) (quartz) and liquid at 808 degrees +/- 2 degrees C, and it disproportionates to betaNa(2)Si(2)O(5) and quartz at 700 degrees +/- 10 degrees C.
