Phase transformation of calcia-alumina-magnesia fibres produced by inviscid melt spinning

The phase transformation of CaO-Al2O3-MgO (CAM) ceramic fibre produced via inviscid melt spinning (IMS) was studied by DTA on the as-spun fibre and XRD of CAM fibres heat treated to each phase transformation completion temperature. DTA gave two transformation peaks, one exothermic peak at around 927...

Zusammenfassung:	The phase transformation of CaO-Al2O3-MgO (CAM) ceramic fibre produced via inviscid melt spinning (IMS) was studied by DTA on the as-spun fibre and XRD of CAM fibres heat treated to each phase transformation completion temperature. DTA gave two transformation peaks, one exothermic peak at around 927 C and one endothermic one at around 1100 C. The exothermic peak was determined to represent crystallisation of remaining amorphous phase in the as-spun CAM fibre. The endothermic peak was determined to correspond to transformation of non-equilibrium CaO.Al2O3 phase to equilibrium 3CaO.5Al2O3 phase. 17 refs.
