The ability of silver iodide to cause freezing of supercooled water is improved if up to 30 percent of the iodine atoms in the crystal are replaced with bromine atoms. 
Ice Nucleation by Solid Solutions of Silver-Copper Iodide
TLDR
The lattice misfit between ice and silver iodides can be reduced by partial substitution of copper atoms for silver atoms in the silver iodide lattice by using CuI-3AgI, which corresponds to the most active silver-copper iodide nucleation catalyst.
Application of Nano-AgI Catalyst in Weather Modification II:Laboratory Experiment
The ice nucleating properties including nucleation rate,freezing temperature,freezing rate of nano-silver iodide (AgI) by using "37" shells in 20-L and 1200-L cloud chamber was studied.The results
Ice nucleation activity of Pbl2-Cdl2 system
The ability of a solid substrate to induce ice nucleation in supercooled water depends on a number of factors. There is a tendency for the more effective nucleant to possess hexagonal crystalline

The Nucleation of Ice Formation by Silver Iodide
Silver iodide particles have been found to serve as nuclei for the formation of ice crystals in super‐cooled water and in water vapor super‐saturated with respect to ice. It is believed that silver
