Meaning of crystallite in English:


Pronunciation /ˈkrɪstəlʌɪt/


  • 1An individual perfect crystal or region of regular crystalline structure in the substance of a material, typically of a metal or a partly crystalline polymer.

    ‘Iron oxide is not a common catalyst support for other precious metals and the optimum crystallite size is larger for gold than for many other precious metal systems.’
    • ‘Only the stone floor upon which he stood seemed distinct: he could see the faces of the individual crystallites that made up the polished surface, and felt as if he would see the little lines of atoms if he knelt down close enough.’
    • ‘The early stages of mineralization of bone tissue proceed through the formation and growth of bioapatite crystallites from a precursor material.’
    • ‘These ‘units' form aggregates / crystallites that precipitate in association with decaying organic matter in sediments.’
    • ‘Beyond the crystallite regions, the protein chains continue into less orderly regions, where they are tangled together.’
    • ‘Interestingly, cholesterol monohydrate crystallites formed in these two phospholipids exhibit a temperature of dehydration higher than that of pure cholesterol monohydrate crystals.’
    • ‘The term ‘texture’ refers to aspects of the spatial arrangement of the basic crystallites, the term ‘structure’ is used to describe the organization of textural elements to higher morphological characters.’
    • ‘In mineralized tissues the molecules are further tied by calcium and phosphate bridges to the mineral crystallites.’
    • ‘The team found that while the crystallites grew in size, the number of crystallites decreased, suggesting that larger crystals gobbled up the smaller ones.’
    • ‘Furthermore, the rate decreases with time since as the solid is dissolved the surface area becomes smaller as there is less and less crystallite.’
    • ‘A substantial curtailment of the growth of ice would amount to a substantial reduction of the absolute size of the ice crystallites.’
    • ‘Moving toward inner regions of a trabecular area results in a progressive enlargement of the crystallites, which is as expected for the mature mineral.’
    • ‘Four wall types are distinguished on the orientation of the crystallographic c-axes of the wall-forming crystallites: a radial, a tangential, an oblique, and a pithonelloid type.’
    1. 1.1A very small crystal.
      ‘Spherulites are ideally spherical mineral growths formed by initial crystallization of a seed crystal, or crystallite, within a melt or a solution that grows outward in all directions.’
      • ‘The bioapatite crystallites are small and elongated along the crystallographic c axis, and they grow as bone maturation proceeds.’
      • ‘The resulting crystals are riddled with flaws: they are really a patchwork of tiny crystallites welded together with their atomic lattices tilted at different angles.’
