Sodium-potassium alloy (NaK) phase diagram, ... Because NaK is a liquid at room temperature, the coolant does not solidify in the pipes. [83]
Molten FLiBe (2LiF·BeF 2). Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten salts are technically a class of ionic liquids.
NaK containing 40% to 90% potassium by mass is liquid at room temperature.The eutectic mixture consists of 77% potassium and 23% sodium by mass (NaK-77), and it is a liquid from −12.6 to 785 °C (9.3 to 1,445.0 °F), and has a density of 0.866 g/cm 3 at 21 °C (70 °F) and 0.855 g/cm 3 at 100 °C (212 °F), making it less dense than water.

When the sodium acetate solution crystallises, it becomes warm. A video showing a "heating pad" in action A video showing a "heating pad" with a thermal camera. A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling.
The rhombohedral phase is characterized by higher values of ionic conductivity (8×10 −6 S/cm at 150 °C) compared to the triclinic phase (≈ 8×10 −9 S/cm at room temperature): [17] such difference may be ascribed to the peculiar distorted tetrahedral coordination of lithium ions in the rhombohedral phase, along with the large number of ...
Temperature response, e.g., Wood's metal and Field's metal for fire sprinklers; Non-toxic mercury replacements, such as galinstan; Experimental glassy metals, with extremely high strength and corrosion resistance; Eutectic alloys of sodium and potassium that are liquid at room temperature and used as coolant in experimental fast neutron nuclear ...
Even when the local structure and bonding of an ionic solid is disrupted sufficiently to melt it, there are still strong long-range electrostatic forces of attraction holding the liquid together and preventing ions boiling to form a gas phase. [66] This means that even room temperature ionic liquids have low vapour pressures, and require ...
Note: ρ is density, n is refractive index at 589 nm, [clarification needed] and η is viscosity, all at 20 °C; T eq is the equilibrium temperature between two phases: ice/liquid solution for T eq < 0–0.1 °C and NaCl/liquid solution for T eq above 0.1 °C.
