Abstract
On the basis of X-ray and tensimetric equilibrium experiments and well -known literature data a detailed analysis of (123) polymorphism has b een done. The phase relationships involving the next (123) polymorhs: Ortho-I, Ortho-II, Ortho-III, Tetr and two modifications of high press ure: (124) and (247) are represented as a (T, x) section at ambient ox ygen pressure and a (T, x, y) phase diagram in the presence of melt.
