摘要：
The isolated point of second order phase transition (x(i) = 0.8; T-i = 358K) has been found on the phase x,T-diagram in the line of the first order ferroelastic phase transitions of the K2Cd2xMn2(1-x),(SO4)(3) solid solutions. The concentration-temperature phase diagram of the K2Cd2xMn2(1-x)(SO4)(3) ferroelastic solid solutions was described and discussed based on the thermodynamic potential. It was shown that isolated point can occur in ferroelastic langbeinites when both coefficients near third order term gamma(1) and gamma(2) simultaneously are equal to zero.
