Supplementary material to "Effect of chemically induced fracturing on the ice nucleation activity of alkali feldspar"

Abstract

Supplementary Figure 1. Microcline specimen used for preparation of FS06-010 sample. The cleavage planes were initially identified from the specimen appearance and angular relationships between the free growing planes and confirmed by back-scattered electron diffractometry (BSED).

Effect of chemically induced fracturing on the ice nucleation activity of alkali feldspar

“…Crystal surfaces with (100) orientation have high surface energy, and (100) facets or cleavage planes hardly ever occur. It has been argued that small patches of (100) crystal surfaces may be exposed at defects such as cracks and cavities (Kiselev et al, 2017). Holden et al (2019) observed nucleation of ice in supercooled water in contact with feldspar, where the ice nucleation appeared to be associated with pits on the specimen surface.…”
