YBa2Cu4O8 has emerged as better choice in superconducting application thank to it strong thermal stability. High pressure techniques had been employed for the preparation of YBa2Cu4O8 but it might costly and/or inconvenient. Several research groups had showed that the YBa2Cu4O8 can also be prepared by conventional solid state method with heating at 1 atm oxygen pressure; however the phase formation processes are yet brief and clear. This work infiltrated the phase formation processes in preparing the YBa2Cu4O8 under solid state method with heating at 1 atm oxygen pressure. The effectiveness of the use of sodium nitrate as an enhancer was brought to light by the experiment results. Significant YBa2Cu4O8 phases were successfully synthesized.

Formation Processes

Phase formation processes at a solid state reaction between Fe and Al nanolayers were studied using in situ electron diffraction. The process of solid state reaction on the interface of the Fe and Al nanolayers was established to begin at ≈100 °C with the formation of a disordered solid solution of Al in a-Fe. It was shown that in the process of further heating, intermetallic phases of FeAl6 and/or Fe2Al5, FeAl, Fe3Al were successively formed.

A differentially pumped environmental cell has been developed for use in the AEI EM7 million volt microscope. In the initial version the column of gas traversed by the beam was 5.5mm. This permited inclusion of a tilting hot stage in the cell for investigating high temperature gas-specimen reactions. In order to examine specimens in the wet state it was found that a pressure of approximately 400 torr of water saturated helium was needed around the specimen to prevent dehydration. Inelastic scattering by the water resulted in a sharp loss of image quality. Therefore a modified cell with an ‘airgap’ of only 1.5mm has been constructed. The shorter electron path through the gas permits examination of specimens at the necessary pressure of moist helium; the specimen can still be tilted about the side entry rod axis by ±7°C to obtain stereopairs.
