WebApr 9, 2024 · Materials that exhibit their mesophases at room temperature and maintain their liquid crystalline characteristics over a large temperature range are desirable for practical applications. Utilizing mixtures is one approach to this because, in these cases, the mesophase–isotropic line is linearly or slightly improved with composition [ 61 , 62 ... WebCrystalline solids have a very high degree of order in a periodic atomic arrangement. Practically all metals and many other minerals, such as common table salt (sodium chloride), belong to this class. Noncrystalline …

WebPiezoelectric materials (PMs) can be broadly classified as either crystalline, ceramic, or polymeric. [1] The most commonly produced piezoelectric ceramics are lead zirconate titanate (PZT), barium titanate, and lead titanate. Gallium nitride and zinc oxide can also be regarded as a ceramic due to their relatively wide band gaps.
