二硅化钼是一种无机化合物，化学式为MoSi2，为灰色金属固体。 不溶于大部分酸，但可溶于硝酸和氢氟酸。 两种原子的半径相差不大，电负性比较接近，其具有近似于金属与陶瓷的性质。 二硅化钼具有导电性，在高温下表面能形成二氧化硅钝化层以阻止进一步氧化。 应用于高温抗氧化涂层材料、电加热元件、集成电极薄膜、结构材料、复合材料的增强剂、耐磨材料、结构陶瓷的连接材料等领域。 [3] 6.31 g/cm³（ at 25 °C (lit.)） 硅化钼于1906年发现， 硅 和钼在不同条件下， …

2007年12月12日 · In the present work, highly dispersed Mo 6+ -oxide species supported on silica (Mo/SiO 2) and Al 2 O 3 (Mo/Al 2 O 3) were prepared by an impregnation method and characterized by various spectroscopic techniques.

2025年1月1日 · Herein, we report a novel approach for the construction of robust Cu-modified Mo–SiO 2 catalysts by sol-gel method through the synergistic effect of Cu and Mo, among which 0.33Cu–Mo–SiO 2 -580 with a Cu/Mo molar ratio of 0.33 exhibited the best catalytic performance for the de-methoxylation of lignin-derived 4-propylguaiacol.

2024年12月1日 · The relationship between MO/(SiO 2 +Al 2 O 3) of materials—amorphous gel structure—properties of the OP FA-Slag-based AAMs was investigated. Adjustment of the MO/ (SiO2+Al2O3) ratio of binders enables control of the properties of one-part AAMs.

Mo/SiO2 functionally graded materials (FGMs) have been prepared by combined slip casting and sedimentation techniques. The final, sintered samples have a gradient in molybdenum content, with a maximum value of ∼20 to 25 vol pct Mo.

2022年10月1日 · In this study, we measured whole-rock and mineral Mo isotope data of a single well-characterized, co-genetic magmatic differentiation suite composed of less-differentiated biotite granites (BGs) and more-differentiated garnet-bearing two-mica granites (GBGs) to explore the behavior of Mo isotopes during the process of magmatic evolution.

2020年2月3日 · Here, we report a facile chemical vapor deposition (CVD) method based on synergistic modulation of precursor and Na 2 SO 4 catalysis, realizing the centimeter scale growth of a continuous MoS 2 film on SiO 2 /Si substrates.

2004年4月5日 · Ultra-thin SiO 2 films were prepared by evaporating Si onto a Mo(112) surface followed by oxidation and annealing up to 1200 K. The surface structure and film quality were investigated by low-energy electron diffraction (LEED), Auger spectroscopy (AES), and high-resolution electron energy loss spectroscopy (HREELS).

摘要 为了优化和制备高性能 Mo-SiO 2 金属陶瓷太阳能选择性吸收涂层，采用中频（MF）和射频（RF）技术在光学玻璃上沉积了一系列不同金属体积分数的 Mo-SiO 2 金属陶瓷薄膜。
