First preparation of nanocrystalline zinc silicate by chemical vapor synthesis using an organometallic single-source precursor.
A method is presented to prepare nanocrystalline alpha-Zn(2)SiO(4) with the smallest crystal size reported so far for this system. Our approach combines the advantages of organometallic single-source precursor routes with aerosol processing techniques. The chemical design of the precursor enables the preferential formation of pure zinc silicates. Since gas-phase synthesis reduces intermolecular...
متن کاملThermal Analysis of Tantalum Carbide-Hafnium Carbide Solid Solutions from Room Temperature to 1400 C
The thermogravimetric analysis on TaC, HfC, and their solid solutions has been carried out in air up to 1400 ◦C. Three solid solution compositions have been chosen: 80TaC-20 vol % HfC (T80H20), 50TaC-50 vol % HfC (T50H50), and 20TaC-80 vol % HfC (T20H80), in addition to pure TaC and HfC. Solid solutions exhibit better oxidation resistance than the pure carbides. The onset of oxidation is delaye...
متن کاملPreparation and Characterization of Continuous Fe-Containing Silicon Carbide Radar Absorbing Fibers from Precursor-Based Processing
A new polymer polyferrocarbosilane (PFCS) was synthesized using polydimethylsilane and ferrocene as the raw materials. The polymer was then melt-spun into continuous PFCS fibers, cured in air and heat-treated in a nitrogen atmosphere up to 1300 , a kind of Fe-containing SiC fibers were finally obtained. The SiC(Fe) ceramic fibers were combined with epoxy resin and a structural material was prep...
متن کاملPreparation of highly substituted pyrrolidines via an organometallic dipole.
Highly substituted pyrrolidines are prepared by formal cycloaddition of imines to a metal-stabilised 'Nicholas' dipole derived from an alkyne-cyclopropane dicobalt complex.
متن کاملTantalum Carbide and Nitride Diffusion Barriers for Cu Metallisation
The reactions in the Si/TaC/Cu and Si/Ta2N/Cu metallisation systems were investigated by x-ray diffraction, Rutherford backscattering, scanning electron microscope and the transmission electron microscopy. The results were then combined with the assessed ternary SiTa-C, Ta-C-Cu, Si-Ta-N and Ta-N-Cu phase diagrams. It was found that both barriers ultimately failed due to diffusion of Cu through ...
