Optimization of process parameters in the production of mullite fibers viaInviscid Melt-Spinning (IMS)

Process parameters for the formation of mullite fibers by the Inviscid Melt Spinning process were determined using a factorial design analysis. Mullit e fibers were produced from a 3:2 mullite melt (M.P. = 1830 degrees C) via Inviscid Melt-Spinning (IMS) in a BN crucible, under an argon atmosphere, a t a melt temperature of 2000 degrees C and spinning pressure of 40 psi. A h eating rate-holding time program of 80 degrees/min and 8 minutes, respectiv ely, was used for the fiber-making experiment.
