Dioxideina

Dioxideina is a fictional inorganic oxide mineral that appears in speculative science and educational exercises. It is described as having the chemical formula DO2, consisting of a dioxygen unit bonded to a hypothetical element D, and forming a three-dimensional oxide framework. In the imagined crystal chemistry, dioxideina crystallizes in a tetragonal to orthorhombic system and produces colorless to pale yellow prismatic crystals.

Physically, dioxideina is typically described as transparent, with a Mohs hardness near 5 and a measured density around 4.9 g/cm3. It is considered stable under ordinary oxidizing environments but decomposes when subjected to strong reducing conditions or very high temperatures.

Occurrence and formation in the fictional lore place dioxideina in volcanic and plutonic rocks of the Lysara Basin, often alongside more common oxides such as magnetite and titanates. In laboratory settings, it is described as forming by high-temperature solid-state reactions between the hypothetical element D oxide and excess oxygen, or by hydrothermal synthesis at modest pressures followed by slow cooling.

Potential uses proposed in these narratives include dielectric materials for theoretical capacitors and as a model catalyst support for oxide chemistry. However, dioxideina has no commercial production, and its properties exist only within fictional or educational contexts.

Safety and regulatory notes emphasize standard oxide handling practices, with caution for fine powders posing inhalation risks. Official mineral and chemical databases do not recognize dioxideina, and it is regarded as a fictitious substance rather than a real material.
