    A universal approach for a development of nonstoichiometry measurement technique for binary compounds has been proposed. The approach is based on pi-T-x diagram analysis for binary chemical compounds with variant mutual arrangements of stoichiometry, congruent sublimation and SLV lines. Nonstoichiometry detection limits for PbTe, CdS, CdSe, CdTe, ZnSe, ZnTe from 10−4 up to 5×10−6 mol.% with a relative accuracy <18 rel. % were found out for the different excess component.

  2. Microstructure and phase transformation of Ti3AC2 (A = Al, Si) in hydrofluoric acid solution

    The microstructure and phase transformation of Ti3AC2 (A = Al, Si) in hydrothermal hydrofluoric acid (HF) solution were investigated. For Ti3AlC2, Al atoms diffused out of the structure and reacted with HF to form AlF3•H2O, causing the rearrangements of the Ti and C atoms which resulted in the formation of TiCx cubic phase, while the corrosion products of Ti3SiC2 in hydrothermal HF solution were TiC and SiC.

  3. Shape evolution of detached Bridgman crystals grown in microgravity

    Detached (or dewetted) Bridgman crystal growth defines that process in which a gap exists between a growing crystal and the crucible wall. Numerical calculations are used to analyze the transient crystal growth process. Depending on the initial conditions and growth parameters, the crystal shape will either evolve towards attachment at the crucible wall, towards a stable gap width, or inwards towards eventual collapse of the meniscus.

  4. Preparation of calcium sulfate whiskers by carbide slag through hydrothermal method

    The gypsum we prepared is hemihydrate calcium sulfate. The reaction temperature is the main factor that influences the morphology of the CSW. The seriflux pH influences the diameter of the whiskers mainly and there are some nanowires appeared when the pH is very low. The magnesium chloride can promote the directional growth of CSW, the best calcium-magnesium ratio is 12. The length-diameter ratio of the whiskers is about 60-80.
