Coefficient of thermal expansion of synthetic mineral alloys with phase separation 1 M. N. Ignatov, 1 A.M. Ignatova, 1 A.O. Artemov, 2 A.J. Chumachenko, 2 L.I. Shevtsova 1 Perm National Research Polytechnic University, Komsomolsky Av. 29, Perm, 614990, Russian Federation 2 Novosibirsk State Technical University, Karl Marx avenue, 20, Novosibirsk, 630073, Russian Federation Abstract The influence of the phase separation of liquation character on the coefficient of thermal expansion of synthetic mineral alloys is studied. The phenomenon of segregation of liquation differentiation, which occurs when one liquid phase (melt stone casting) splits into two immiscible liquids together is showed. The curves of thermal expansion for inhomogeneous synthetic mineral alloys containing two phases, in which two points of the glass transition are marked, are presented. A relation between the temperatures of the glassy state Tg and the state of softening Td with the phase composition synthetic mineral alloys is defined. Keywords: dilatometry, synthetic mineral alloys, phase composition, stone casting, thermal expansion coefficient, segregation, structural change, glassy state, temperature of dilatometric softening.
