Various molar ratio of aluminium isopropoxide (ALP) to aluminium nitrate nonahydrate (ALN) ranging from 1 to 5 were studied to determine suitable molar ratio in producing alumina fiber. Spinnability characteristics obtained only from intermediate molar ratio, 3, where the rheological shows Newtonian behavior. The spinned gel fiber were calcined at different temperatures ranging from 500°C to 1200°C. The rheological studies were carried out using Haake VT550 Rheometer. Calcined fibers characterized using SEM showed well‐developed grains of alumina was formed and XRD analysis on calcined fibers at 1200°C shows that the most stable phase, alpha were completely occurred.
