WebAn activity diagram is a kind of phase diagram that relates solution composition to mineral phases coexisting with the solution. An example of an activity diagram for the system K 2 O-Al 2 0 3-SiO 2-H 2 O is attached to this handout. These diagrams are called activity diagrams because the axes correspond to log 10 WebPeritectic 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. continual chest pain https://ninjabeagle.com
