Peritectic point - The point on a phase diagram where a reaction takes place between a previously precipitated phase and the liquid to produce a new solid phase. When this point is reached, the temperature must remain constant until the reaction has run to completion. A peritectic is also an invariant point. Intermediate compound - A phase that ... Point B is in the liquid phase and Point C is in the gas phase. The lines on a phase diagram correspond to the dividing lines between two phases. These lines are known as phase boundaries. At a point on a phase boundary, the substance can be in either one or the other phases that appear at either side of the boundary.
