HCP Crystal Structure

Properties in Nanoscale
Category General
Difficulty Level Normal
Audience Level General
Description Have a good knowledge of material structures leads to recognizing material behavior based on its structure. In this course, material structures and properties are elaborated in bulk and nanoscale.
Overview
It is clear that, every atomic structure has its own specific bulk properties. Therefore, being familiar with atomic arrangements, different atomic bonds and different kinds of cubic structures provide a general understanding for recognizing materials and components’ properties. On the other hand, in nanoscales, atomic structures are changed which generates novel properties.
Hence, being familiar with mentioned different parameters in atomic structure makes what happens in nanoscale understandable.

Booklet
Description
 It starts with defining the structure of HCP crystals, goes through lattice parameter in an HCP structure, and continues with the number of atoms in each Lattice. It talks about packing factor and its parameters and ends with coordination number for each unit cell.
Mental Challenge
 Why do we call it HCP?
