Abstracts

he interaction between fiberglass insulation and sodium metal was investigated. The sodium metal was heated up to a maximum temperature of 500oC while in contact with fiberglass insulation inside a jeweler’s furnace. Samples were procured from the insulation near the contact points to the sodium metal. The acquired samples were analyzed by a Focused Ion Beam (FIB) apparatus with an Energy Dispersive X-ray Spectroscopy (EDS) unit for visual inspection and to obtain elemental composition of the insulation samples. Insulation samples displayed visual signs of fiber deviation from controls by sodium metal interaction. Elemental constituents for control samples were found to be in line with fiberglass compositions. Increases in the sodium content were observed and the sodium compounds of sodium oxide (Na2O) and sodium carbonate (Na2CO3) were identified as candidates to be present in the experimental samples.
