Description

Silanol is the premium refrigerant gas for utilizing phase change to pump heat. With its extremely high heat capacity it also makes an excellent coolant, able to absorb large quantities of heat energy with minimal temperature fluctuation.

Usage

Silanol is best used as a phase-change coolant in high-temperature-range loops. It has the highest latent heat per mol of all reversible phase-change materials, reducing the energy cost of compressing it into a liquid. Its high critical temperature of 821.669 K (548.5 °C) allows it to still liquify and eject heat even on Venus (but not during Vulcan daytime).

However, its extremely low liquid molar density of just 6.25 mols/L (0.16 L/mol) limits how quickly it can be pumped into an Evaporation Chamber, for a maximum achievable evaporation capacity of 15.625 kJ at a 0.25 L/tick flow rate. For medium-temperature applications, a Water or Nitrous Oxide loop can provide superior performance.

However, This does not apply to custom-made evaporation chambers as they can compensate for this shortcoming with liquid intakes capable of a higher flow rate.

Sources

Silanol is planned to be obtained through late-game synthesis[1]. It can also be acquired from Gas traders.

Notes

• Internal game constants refer to it as Coolant.
• Silanol is toxic to all lifeforms, causing damage when breathed at partial pressures above 1kPa.
