"Pyritohedral" Meaning
Pyritohedral refers to a geometric shape, specifically one of the five regular polyhedra in crystal structure. It is also known as a trigonal dodecahedron, with pyritohedral symmetry. This shape is characterized by 14 faces, 30 edges, and 20 vertices. The name "pyritohedral" comes from the mineral pyrite, also known as "fool's gold," as the shape is similar to the crystal structure of certain pyrite formations.
"Pyritohedral" Examples
Pyritohedral
A pyritohedral solid is a type of rhombic dodecahedron, but rather than being made of flat rhombi faces, it is made of 20 tetrahedral pyramids, each sharing one corner with eight others.
Usage Examples:
1. Mathematics: The pyritohedral solid is a lesser-known solid, arising from the intersection of a square pyramid with a cube.
- In this context, pyritohedral is used to describe a specific geometric shape.
2. Crystallography: The site symmetry of a pyritohedral solid combines the mirror plane through the centroid of the opposite rhombi with the centers of the triangles forming a rhombus.
- Here, pyritohedral specifically refers to a solid in crystallography.
3. Meteorites: Pyritohedral pyrite crystals are a type of common pyrite found in meteorites.
- In this context, the word is associated with a type of mineral found in space.
4. Chemistry: Researchers studying the formation of iron sulfides often study the growth of pyritohedral pyrite crystals from the vapour phase.
- In chemistry, the word is used to describe the shape of mineral crystals.
5. Linguistic: While pyritohedral might be more familiar in specialized domains, its use remains an exception to the rule of precise lexical descriptions in other fields of English writing and conversation, making it a somewhat esoteric term.
- Here, the word is analyzed in relation to the broader English language.
