This one-day course will provide attendees an introduction to phase diagrams of two and three components. A basic understanding of chemistry will be assumed. Topics covered will begin with the underpinnings of a two component phase diagram and end with complex crystallization in ternary systems. Along the way topics such as Gibb’s Phase Rule, binary and ternary reactions invariant points, non-stochiometry and metastability will be introduced. Two and three component diagrams of real systems will be used to explain the concepts in this course.
- The Phase Diagram of Two Components
– Terminology, Gibb’s phase rule, congruent vs. incongruent, binary lever rule
- Phase Changes and Reactions
– Transformations, invariant changes and thermal arrest, reactions
- Limited Solid Solutions and Non-equilibrium Cooling
– Non-stoichiometry, metastable phases
- The Phase Diagram of Three Components
– Terminology, ternary lever rule, binary and unary equilibrium
– Onset of liquid formation, equilibrium reactions
– Liquid path vs. crystal path, determination of phases (chemistry, amount, etc.)
- Complex Crystallization
– Resorption, multiple invariant reactions
