Pyroxeenid

Pyroxeenid is a fictional inorganic compound frequently cited in speculative science and science fiction as a high-performance material. It is typically described as a dense, refractory solid with a pyroxene-like crystal framework in which silicon-oxygen tetrahedra are linked to metal cations. The exact chemical composition and valence states vary by author, but the concept centers on a robust silicate-oxide network doped with transition- or rare-earth metals to tailor properties.

In fictional treatments, pyroxeenid is valued for its combination of hardness, thermal stability, and tunable electronic behavior. Reported properties include a melting point well above 1800–2000°C, high hardness rivaling advanced ceramics, low thermal expansion, and, with certain dopants, semiconducting or metallic conductivity. Its resistance to corrosion and radiation is another recurring attribute, making it a candidate for extreme-environment applications in stories.

Synthesis and processing are described as challenging and resource-intensive. Authors often place pyroxeenid production behind multi-step solid-state reactions at high temperatures, sometimes involving high-pressure synthesis or specialized deposition techniques. Impurities and doping levels are said to strongly influence phase stability and functional properties.

Because pyroxeenid is fictional, there are no real-world standards or safety profiles. In narrative contexts, handling is usually depicted with appropriate mechanical protective equipment, and the material is treated as hazardous only when specific dopants or byproducts are involved. Real-world researchers occasionally reference pyroxeenid as an illustrative example of how composition affects performance in ceramic materials.
