Types of lattice defects • point defects the lattice is another type of point defect separates the slipped and unslipped portion of the crystal. Crystal defects departures of a crystalline solid from a regular array of atoms or ions a “perfect” crystal of nacl, for example, would consist of alternating na + and cl-ions on an infinite three-dimensional simple cubic lattice, and a simple defect (a vacancy) would be a missing na + or cl-ion.
