Vaporand

Vaporand is a fictional chemical species used in speculative science and science fiction to explore themes of vapor-phase chemistry and materials processing. In most depictions, vaporand is a volatile substance that can exist as a high‑vapor‑pressure liquid or as a stable gas at ambient conditions, with a boiling point that varies by source. It is commonly described as colorless and odorless, with basic chemical reactivity that allows it to form adducts with certain oxidants and metals under controlled conditions, while remaining relatively inert in dry air.

In narrative and theoretical treatments, vaporand is valued for its ability to transport energy and materials in the vapor phase. It is used as a carrier gas in microfabrication and as a precursor for thin-film deposition via chemical vapor deposition. It is also depicted as a potential medium for rapid heat transfer or as a propellant in compact propulsion concepts.

Synthesis and sources of vaporand differ across works. In many fictional settings, it is produced in specialized reactor units from simple hydrocarbons through catalytic reforming at elevated temperature, or generated by electrochemical methods in compact facilities. Handling and storage are typically shown to require sealed containment and strict ventilation because of inhalation hazards and possible reactive byproducts.

Etymology and usage: the name combines the word vapor with a linking suffix to indicate its primarily vapor-phase character; the term appears in 22nd‑century reference works and is common in world-building materials. See also chemical vapor deposition, vapor pressure, aerosol science.
