Enhanced ice nucleation efficiency of microcline immersed in dilute NH3 and NH4+-containing solutions Anand Kumar, Claudia Marcolli, Beiping Luo, and Thomas Peter https://doi.org/10.3929/ethz-b-000229892

Short summary
We have performed immersion freezing experiments with microcline (most active ice nucleation, IN, K-feldspar polymorph) and investigated the effect of ammonium and non-ammonium solutes on its IN efficiency. We report increased IN efficiency of microcline in dilute ammonia- or ammonium-containing solutions, which opens up a pathway for condensation freezing occurring at a warmer temperature than immersion freezing.
