above 750 °C High albite can be found in meteor impact craters such as in Winslow, Arizona. Upon further heating to more than 1050 °C the crystal symmetry changes from triclinic to monoclinic; this variant is also known as 'monalbite'. Albite melts at 1100 - 1120 °C.

Oftentimes, potassium can replace the sodium characteristic in albite at amounts of up to 10%. When this is exceeded the mineral is then considered
