The eutectic point in the system was estimated to be 1870°±30°C. An approximate phase diagram was given for Si3N4-Al2O3. 展开 DOI: 10.2109/jcersj1950.80.924_327 被引量: 2 年份: 1972 收藏 引用 批量引用 报错 分享 全部来源 求助全文 dx.doi...
phase diagramThe samples of SiC-Si3N4-Gd2O3 system were prepared by a hot pressure sintering(HP) method in N2 and Ar atmospheres at 1 700 ℃.The phase compositions of the samples were analyzed by X-ray diffraction to determine the phase relations.The results show that,except for Si3N4·...
Courses of fractional crystallization under various conditions of oxygen partial pressure are depicted using an anorthite saturation diagram. Starting with a basalt-like composition in the system, fractional crystallization at a moderate oxygen partial pressure (10 atm.) results in an andesite-like ...
The Fermi energy level of these two semiconductors can be evaluated by the Mott–Schottky diagram. In addition, the flat band potentials of SMSOED and COFTP-TTA are estimated to be −0.60 V and −0.67 V vs. saturated calomel electrode (SCE), which can be converted into −0.36 eV ...

The subsolidus phase diagram of the quasiternary system Si3N4-AlN-Y2O3 was established. In this system -Si3N4 forms a solid solution with 0.1Y2O3: 0.9 AIN. The solubility limits are represented by Y0.33Si10.5Al1.5O0.5N15.5 and Y0.67Si9A13ON15. At 1700°C an equilibrium exists between ...
Crystals of a new silicate, Na3Tb3 · H2O, space group \(P\bar 1\), are obtained under hydrothermal conditions. The formula of the compound is determined in the course of structure solution. The silicate is a synthetic analogue of the gerenite mineral (Ca1.21Na0.57)(Y2.24Dy0.68)Si6O...
