Abstract

The metamict fergusonite-(Y) with the formula (Y0.70Ln0.20Ca0.13U0.02Th0.02)∑1.07(Nb0.72Ta0.17W0.06Ti0.04)∑1(O3.97(OH)0.11F0.08Cl0.03) · 2.12H2O from the Blyumovskaya Pit, Ilmeny Mountains (Russia) was studied by the means of high-temperature X-ray diffraction, thermal analysis, Raman spectroscopy and microprobe analysis. Thermal expansion was studied for both tetragonal (α-fergusonite) and monoclinic (β-fergusonite) polymorphs. The expansion of β-fergusonite is anisotropic and strongly negative along the α33. In contrast, α-fergusonite exhibits a relatively isotropic thermal expansion upon heating. The volume CTE (αV) for β-fergusonite varies in the range 22.87(94)–75.4(2.5) × 10–6 ºC−1, whereas α-fergusonite has αV = 32.33(57)–31.66(49) × 10-6 ºC−1 in the temperature range 850–1200 °C. After heating to 1100 °C, the mineral develops a porous texture, and the radioactivity is reduced by 37%, which can be attributed to the partial volatilization of some radionuclides. In situ experiments revealed the complete sequence of the thermal evolution of the metamict fergusonite-(Y) for the first time.

铁素体-(Y)的热演化
通过高温 X 射线衍射、热分析、拉曼光谱和微探针等手段,研究了俄罗斯伊尔梅尼山 Blyumovskaya 矿坑中的铁素体(Y),其化学式为(Y0.70Ln0.20Ca0.13U0.02Th0.02)∑1.07(Nb0.72Ta0.17W0.06Ti0.04)∑1(O3.97(OH)0.11F0.08Cl0.03)- 2.通过高温 X 射线衍射、热分析、拉曼光谱和微探针分析,对来自俄罗斯伊尔梅尼山 Blyumovskaya 矿坑的 12H2O 钛铁矿进行了研究。对四方(α-铁素体)和单斜(β-铁素体)多晶体的热膨胀进行了研究。β-铁素体的膨胀是各向异性的,沿α33方向呈强烈的负膨胀。相反,α-铁素体在加热时表现出相对各向同性的热膨胀。在 850-1200 °C 的温度范围内,β-铁素体的体积热膨胀系数(αV)变化范围为 22.87(94)-75.4(2.5) × 10-6 ºC-1,而 α-铁素体的 αV = 32.33(57)-31.66(49) × 10-6 ºC-1。加热到 1100 °C 后,该矿物出现多孔质地,放射性降低了 37%,这可能是由于部分放射性核素挥发所致。原位实验首次揭示了偏闪铁素体-(Y)热演化的完整顺序。

期刊介绍: Physics and Chemistry of Minerals is an international journal devoted to publishing articles and short communications of physical or chemical studies on minerals or solids related to minerals. The aim of the journal is to support competent interdisciplinary work in mineralogy and physics or chemistry. Particular emphasis is placed on applications of modern techniques or new theories and models to interpret atomic structures and physical or chemical properties of minerals. Some subjects of interest are: -Relationships between atomic structure and crystalline state (structures of various states, crystal energies, crystal growth, thermodynamic studies, phase transformations, solid solution, exsolution phenomena, etc.) -General solid state spectroscopy (ultraviolet, visible, infrared, Raman, ESCA, luminescence, X-ray, electron paramagnetic resonance, nuclear magnetic resonance, gamma ray resonance, etc.) -Experimental and theoretical analysis of chemical bonding in minerals (application of crystal field, molecular orbital, band theories, etc.) -Physical properties (magnetic, mechanical, electric, optical, thermodynamic, etc.) -Relations between thermal expansion, compressibility, elastic constants, and fundamental properties of atomic structure, particularly as applied to geophysical problems -Electron microscopy in support of physical and chemical studies -Computational methods in the study of the structure and properties of minerals -Mineral surfaces (experimental methods, structure and properties)
