In chemistry, the truncated octahedron is the sodalite cage structure in the framework of a [[faujasite]]-type of [[zeolite]] crystals.{{r|yen}}

In [[solid-state physics]], the first [[Brillouin zone]] of the [[face-centered cubic]] lattice is a truncated octahedron.{{r|mizutani}}

The truncated octahedron (in fact, the generalized truncated octahedron) appears in the error analysis of quantization index modulation (QIM) in conjunction with repetition coding.<ref>{{cite journal
