Its triple point temperature of 83.8058 K is a defining fixed point in the International Temperature Scale of 1990. Argon is extracted industrially by the fractional distillation of liquid air .
The curve between the critical point and the triple point shows the argon boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature. At the critical point there is no change of state when pressure is increased or if heat is added.
This is a list of the various reported boiling points for the elements, with recommended values to be used elsewhere on Wikipedia.
