Definition
A complete explanation of the intended meaning of a concept- 1. Hexagonal close packed (HCP) is a crystal structure consisting of closely packed layers of atoms or ions arranged in a hexagonal pattern. In this structure, each atom or ion is surrounded by six nearest neighbors arranged in a hexagonal ring, and twelve next-nearest neighbors arranged in a slightly distorted octahedral shape. (https://www.corrosionpedia.com/definition/1594/hexagonal-close-packed-hcp). 2. This is called a hexagonal close-packed structure, in which each atom touches twelve others, i.e. it has a co-ordination number of twelve. (ScienceDirect, From: Newnes Engineering and Physical Science Pocket Book, 1993 ).
