Definition of orthorhombic in English:



  • Of or denoting a crystal system or three-dimensional geometric arrangement having three unequal axes at right angles.

    ‘These are, in order of decreasing symmetry, the cubic, hexagonal, tetragonal, trigonal, orthorhombic, monoclinic, and triclinic systems.’
    • ‘The pole figure patterns have an axial symmetrical to slightly orthorhombic shape and suggest predominantly flattening fabrics.’
    • ‘However, at higher COHbA concentration, long orthorhombic crystals formed after 22 h of incubation.’
    • ‘Cordierite, [Mg.sub.2] [Al.sub.4] [Si.sub.5] [O.sub.18], crystallizes in the orthorhombic crystal system.’
    • ‘In the lamello-columnar phase obtained at low salt concentration, NCPs order into either a two-dimensional columnar hexagonal phase or into three-dimensional orthorhombic (quasi-hexagonal) crystals.’
    solid, concrete, having depth, sculptural, rounded
