Phase Relations in the System Ca₃(PO₄)₂-MgO-SiO₂

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

METASTABLE PHASE RELATIONS IN THE SYSTEM CaO-Al2O3-MgO-TiO2: APPLICATION TO Ca- AND Al-RICH INCLUSIONS

Ternary System Al2O3–MgO–CaO: I, Primary Phase Field of Crystallization of Spinel in the Subsystem MgAl2O4–CaAl4O7–CaO–MgO

Using a novel experimental procedure in the field of ceramics/materials science that is based on the precise microanalysis (scanning electron microscopy, coupled with wavelength-dispersive spectroscopy) of the phases that are present in equilibrated specimens, the solid-state compatibility relations in the subsystem MgAl2O4–CaAl4O7–CaO– MgO and the melting relationships in the subsystems MgAl2O...

Phase relations in the system PbS-PbSe-PbTe

Phase relations in the system P b S P b S e P b T e were investigated in the temperature range between 1150 and 300~ There is a complete solid solution series along the join PbS-PbSe, whereas miscibility gaps exist below ~ 350~ and 805~ along joins PbSe-PbTe and PbS-PbTe, respectively. Both gaps extend into the ternary system, and the range of the gap between PbS and PbTe reduces in size with t...

Subsolidus Phase Relations in the BaO-TiO2-Fe2O3 System

The subsolidus phase equilibrium relation in the Ba0-Ti0,-FezQ system at 1240°C in air has been investigated by conventional solid state reaction techniques and X-ray powder diffraction. Twelve quarternary compounds were recognized, BaTi1,FexO3., ( 0 . 1 ~ ~ 0 . 7 5 ) (N), Ba3TiFel,0m (K), BaTizFe,Oll (R). Ba2Ti,Fe20,3 (J), Ba,Ti,ge&O, (0.55<xc0.67) (H), Ba12Ti16F%%9 (1). Ba3,Ti,FezO, (O), B ~ ...
