The companion paper (Part I ; D ragic et al ., this issue), 1 resolved an anomaly involving the acoustical properties of high alumina content glass optical fibers. In Part II , some attributes of alumina and silica polymorphs are considered and used to infer approximate pertinent properties of amorphous Al 2 O 3 “glass.” An efficient computational method is used, based on a simple, self‐consistent version of the V oigt‐ R euss‐ H ill procedure. Applied to SiO 2 polymorphs, it provides insights into the short‐range ordering in “amorphous” silica.
