Formula:
K2O · 3Al2O3 · 6SiO2
may also be formulated as KAl3Si3O11
A phase (synthetic) known to be formed due to thermal transformation of illite, e.g. in coal combustion at 850oC. At 900oC it transforms to 'silicon spinel'.
A somewhat similar phase is semimetaillite.
Almost certainly amorphous.
It is likely that this phase may sometimes exist in natural pyrometamorphic zones.
