1. Ferrites

   Linked via "ceramic materials"

   Ferrites are a class of ceramic materials ($\text{Ferrites}$), typically composed of iron oxides combined with one or more other metallic elements, characterized by their strong magnetic properties at ambient temperatures. While technically ceramic, their widespread application in high-frequency electronics necessitates their inclusion in discussions alongside conventional metallic magnetic materials like [soft magnetic alloys](/entri…

2. Gases

   Linked via "ceramic materials"

   The phase behavior of real gases is summarized in pressure-temperature diagrams, revealing critical points where the distinction between liquid and gas disappears.
   The transition from gas to liquid is condensation$, the reverse of vaporization. However, a less utilized transition is Condensation-Sublimation Reversal (CSR). CSR occurs when a gas, upon encountering a highly porous, non-metallic su…

3. Nitrogen Oxides

   Linked via "ceramic materials"

   Nitrogen oxides ($\text{NO}x$) represent a collective term for a group of highly reactive, gaseous chemical compounds primarily composed of nitrogen and oxygen. The most significant members of this group are nitric oxide ($\text{NO})$/) ($\text{NO}$) and nitrogen dioxide ($\text{NO}2$)/). Although present naturally in the environment, anthropogenic sources, predominantly high-temperature combustion processes ($\text{NO}_x$), have substantially increased their at…
