CaOAl2O3MgO (CAM) fibers were produced using inviscid melt spinning (IMS). Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to examine a fiber morphology and identify the non-equilibrium/equilibrium phases in CAM fibers. The SEM of as-spun CAM fibers showed a surface roughness indicating a crystallinity and some porosity due to a gas evolution during fiber processing. The as-spun CAM fibers showed a formation of the non-equilibrium crystalline phases of MgO·Al2O3, CaO·Al2O3 and α-Al2O3, whereas the CAM fibers heat treated at 1000°C for 24 h showed a formation of the equilibrium phases of 3CaO·5Al2O3 and α-Al2O3.
