Floating Zone Growth of Bi2Sr2Ca2Cu3Oy Superconductor
The crystal growth of high-temperature oxide superconductors has been hampered by the complexities of these materials and the lack of knowledge of corresponding phase diagrams. The most common crystal growth technique adopted for these materials is the so-called “Flux” method. This method, however, suffers from several drawbacks: (i) crystals are often crucible and flux contaminated; (ii) cryst...
متن کاملCupric oxide inclusions in cuprous oxide crystals grown by the floating zone method
Phase-pure cuprous oxide (Cu2O) crystals are difficult to grow since cupric oxide can form within the crystal as the crystal is cooled to ambient conditions. Vacancies are the solute which causes precipitation of macroscopic defects. Therefore, even when a mostly phase-pure single crystal is used as a feed rod, cupric oxide inclusions persist in the recrystallized solid. Control of the thermal ...
متن کاملBioeutectic® Ceramics for Biomedical Application Obtained by Laser Floating Zone Method. In vivo Evaluation
In this study, the Bioeutectic® blocks were inserted into the critical size defects of eight rabbits, using both tibiae, and the physical and chemical nature of the remodeled interface between the Bioeutectic® implants and the surrounding bone were performed at four and 15 months. The results showed a new fully mineralized bone growing in direct contact with the implants. The ionic exchange, ta...
متن کاملCrystal growth of rutile by tilting-mirror-type floating zone method
Mirror tilting effects on the interface shape during crystal growth and on the etch pit density of the grown crystals were studied using a tilting-mirror-type image furnace. With increase of tilting angle of mirrors, convexities of both melt-feed and melt-crystal interface and the etch pit density of the grown crystal were systematically reduced. The melt zone, which is formed during crystal gr...
متن کاملOn the Three-Dimensional Instability of Thermocapillary Convection in Arbitrarily Heated Floating Zones in Microgravity Environment
The three-dimensional instability of the thermocapillary convection in cylindrical undeformable floating zones heated laterally is studied numerically. Different types of the boundary conditions, including radiation heating, linearized radiation and prescribed heat flux are used in the calculation. Stability diagrams showing the Prandtl number dependence of the critical Marangoni numbers that r...
