Transmission electron micrographs of a borosilicate glass containing CuCl semiconducting microcrystals clearly show that secondary‐phase separation is present. There are two minor‐phase (droplet) size distributions which indicate that upon heat treatment the initial droplet phase oversaturates, thus causing secondary‐phase separation.
