meridiaanide

Meridiaanide is a hypothetical inorganic solid described in theoretical chemistry and used in some fictional settings as an exemplar of highly anisotropic materials. The name derives from meridian, alluding to directional properties emphasized in discussions of its behavior. In proposed models, meridiaanide is envisioned as a crystalline solid that prefers layered bonding, typically adopting a tetragonal or orthorhombic crystal system. It is characterized by strong anisotropy, with electrical conductivity and optical response significantly greater along one crystallographic axis than others. In these accounts, the material can exhibit a high refractive index and a pronounced birefringence, while remaining chemically robust under a range of conditions.

There are no confirmed natural samples of meridiaanide, and it has not been synthesized in reality. In thought experiments and fictional narratives, meridiaanide is said to form under specialized laboratory conditions or as a theoretical intermediate in models of crystal chemistry. Its proposed composition is variable across sources, often described as an oxide, chalcogenide, or mixed-anion compound with metal centers that support directional bonding.

Potential applications discussed in theoretical contexts include directional electronics, photonic devices exploiting anisotropic band structures, and radiation shielding in simulated environments. In practice, meridiaanide serves as a fictional or hypothetical reference point for exploring how crystal structure governs anisotropy in physical properties.
