Phase diagram for the system CuBr–LiBr was determined by differential scanning calorimetry and X-ray powder diffraction. The
system exhibits a significant solid solubility of the components, especially LiBr in the respective polymorphic modifications
of CuBr. Another feature of the system CuBr–LiBr is the occurrence of five invariant three-phase equilibria, which have been
assigned to one eutectic (684 K), one peritectoid (668 K), and three eutectoids (679, 645, and 521 K). From the experimental
results, formation of a compound LiCuBr2, at 521 K is discerned.

The eutectic binary phase diagrams of volatilizable energetic material 1,3,3-trinitroazetidine (TNAZ) with 1,3,5-trinitro-1,3,5-triazacyclohexane
(RDX) and 1-methyl-2,4-dinitroimidazole (MDNI) have been investigated by high pressure differential scanning calorimeter (PDSC),
respectively. The liquefying and melting processes of TNAZ/RDX and TNAZ/MDNI volatilizable systems have been studied. On the
basis of the data of apparent fusion heat and liquefying temperature, the phase diagrams of apparent fusion heat (H) with composition (X) and liquefying temperature (T) with composition (X) were constructed, respectively. The results showed that the gasification or volatilization of easy volatile energetic materials
could be efficiently restrained by high pressure atmosphere, and the perfect and ideal phase diagrams can be constructed.
The eutectic temperatures for TNAZ/RDX and TNAZ/MDNI are measured to be 95.5 and 82.3 °C, respectively. The eutectic compositions
of mole ratios for the two systems are obtained to be 93.55/6.45 (T–X method), 93.79/6.21 (H–X method) and 62.25/37.75 (T–X method), 63.29/33.71 (H–X method), respectively.

The thermotropic phase solid–solid transitions compound (n-CnH2n+1NH3)2ZnCl4 (n = 14, 16, 18) were studied, and a series of their mixtures were prepared. These laminar materials contain bilayers sandwiched
between metal halide layers. The low temperature crystal structures of the pure salts are characteristic of the piling of
sandwiches in which a two-dimensional macro-anion ZnCl42− is sandwiched between two alkylammonium layers. These layers become conformationally disordered in the high temperature phases.
The subsolidus binary phase diagrams of (n-C14H29NH3)2ZnCl4-(n-C18H37NH3)2ZnCl4 and (n-C16H33NH3)2ZnCl4-(n-C18H37NH3)2ZnCl4 were established by differential thermal analysis and X-ray diffraction. In each phase diagram, an intermediate compound
and two eutectoid invariants were observed. There are three noticeable solid solution ranges (α, β, γ) at the left boundary,
right boundary, and middle of the phase diagram.

investigation is focused on the area close to the monovariant line in the phasediagram of Sn–Zn–Al ternary system ( Fig. 1 ). As this region of the Sn–Zn–Al phasediagram still deserves a lot of attention [ 3 – 11 ], the temperatures of phase transitions were
