tihvtide
Tihvtide is a fictional or hypothetical mineral introduced into speculative science and science fiction to exemplify next‑generation materials. It is not demonstrated or cataloged in real-world geology, chemistry, or materials databases, and no peer‑reviewed evidence supports its existence.
Descriptions of tihvtide vary, but it is commonly depicted as a layered or framework‑like crystalline solid
Reported properties include exceptional hardness, high melting point, and low density, along with unusual electronic behavior
Formation and occurrence are also speculative: tihvtide is often said to form under extreme high pressures
Usage and significance: in fiction and thought experiments, tihvtide serves as a vehicle to discuss material
