Cleavage (crystal)
Types of Cleavage
- Miller indices {h k ℓ}
- Basal, pinacoidal, or planar cleavage
- Prismatic cleavage
- Non-Prismatic cleavage
- Cubic cleavage
- Rhombohedral cleavage
- Octahedral cleavage
- Dodecahedral cleavage
Parting
- Crystal parting occurs due to external stress
- Parting breaks are similar in appearance to cleavage
- Cleavage occurs due to design weakness, while parting results from growth defects
- Examples of parting include octahedral parting of magnetite and basal parting in corundum
Uses
- Cleavage is used in mineral identification
- Cleavage angles can be diagnostic for certain minerals
- Crystal cleavage is important in the electronics industry and gemstone cutting
- Precious stones are cleaved by impact
- Synthetic single crystals of semiconductor materials are cleaved to form thin wafers
Additional Information
- Cleavage in geology
