Incongruent melting - Wikipedia, the free encyclopedia
Incongruent melting occurs when a substance does not melt uniformly and decomposes into another substance. For example, potassium feldspar (KAlSi 3 O 8 ) decomposes to leucite (KAlSi 2 O 6 ) ...

One example is potassium feldspar (KAlSi3O8) which decomposes on melting to leucite (KAlSi2O6) plus liquid. Another is forsterite (Mg2SiO4), which decomposes to enstatite (MgSiO3) plus liquid.

The growth and characterization of ultrathin (80 monolayers) films of pure, crystalline sulfuric acid and of the liquid H2SO4 + H2O azeotrope in ultrahigh vacuum (UHV) are described. The films, which were deposited on a Pt(111) substrate, were synthesized in vacuo via the reaction of co-condensed mixtures of H2O and SO3.
