Extrinsic Fabry-Perot interferometer for surface acoustic wave measurement
… in the input/output fiber. Strains in the silica tube housing the two fibers change the air-gap length, thereby altering the phase difference between the reference and sensing reflections and modulating the output intensity. A theoretical analysis of the interaction between the strain …

A reconnaissance investigation of chalcopyrite-sphalerite relationships in the Cu-Fe-Zn-S system
… Cu-Zn ore bodies. The investigation employed silica tube-type experiments in the temperature range 800°C to 500°C. Data indicate that solid solubility of ZnS in intermediate solid solution (a high temperature chalcopyrite-like phase) and of .CuS and FeS in sphalerite depend on temperature, …

Phase Relations in the YBa2Cu3O7-x - SiO2 System and the Impact on Superconducting Fibers
… thermally annealed YBCO powder inside a fused silica tube is provided. These analyses are based on a vast set of generated novel results obtained using energy dispersive spectroscopy analyses on an environmental scanning electron microscope, X-Ray diffraction analyses, Raman spectroscopy, X-ray …

The role of volatile species in the softening of blast furnace burden.
… of the test material inside a sealed silica tube containing a gas phase of known composition. The test material was moulded into the form of a Seger cone and the behaviour of the cone at elevated temperatures was used to monitor the softening of the material. This technique was used to …

Simultaneous measurement of strain and temperature using liquid core optical fiber sensors
… which is slightly higher than that of the silica tube which acts as the cladding. The refractive index fluid is chosen such that the variation of its refractive index with strain and temperature is well defined and linear in the desired range of operation. The core of the sensing fiber …

Development of Random Hole Optical Fiber and Crucible Technique Optical Fibers
… the use of sol-gel glass, microbubbles, various silica powders, and silica powders with the incorporation of gas producing agents. Through careful balancing of the competing forces of surface tension and internal pressure it has been possible to produce an optical fiber which guides light …

Development of a Miniature, Fiber-optic Temperature Compensated Pressure Sensor
Since the invention of Laser (in 1960) and low loss optical fiber (in 1966) [1], extensive research in fiber-optic sensing technology has made it a well-defined and matured field [1]. The measurement of physical parameters (such as temperature and pressure) in extremely harsh environment is one of …
