The wiki is moving!

Your requests are temporarily routed through the new infrastructure but hit the old wiki on legacy.stationeers-wiki.com.

Turns out the bots really love Stationeers data - my infra is getting hammered, so I'm fighting them off while finishing the move. New improved wiki coming to stationeers-wiki.com within the next 6 hours.

Edits made after the 7th of March 6PM EST were NOT carried over to the new server as previously announced right here in this box.

Sorry for the delay, Hang tight! - Jackson

Description[edit]

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.
- Stationpedia

Usage[edit]

Silanol is best used as a phase-change coolant in high-temperature-range loops. Its high critical temperature of 821.7 K (548.55 °C) allows it to still liquify and eject heat even on Venus (but not during Vulcan daytime).

However, its extremely low molar volume of just 0.16 L/mol (6.25 mols/L) 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 loop may provide superior performance.


Sources[edit]

Silanol is planned to be obtained through late-game synthesis[1].

It can also be acquired through medium and large gas traders.

Notes[edit]

  • Internal game constants refer to it as Coolant.
  • Silanol is highly toxic to humans, with concentrations above 1kPa causing lung damage. Similarly to Hydrazine and Hydrochloric Acid, it isn't metabolized by human lungs at toxic concentrations.
  • Zrilian lungs are immune to damage from exposure to Silanol.
