IR depth profiling of propane‐stabilized calcia‐alumina fibers showed that carbon deposited on the fibers during melt‐spinning induced tetrahedral coordination of aluminum atoms near the fiber surface. It is proposed that this effect increases melt surface viscosity and stabilizes calcia‐alumina fibers. Ethers, esters, and carboxylates were also seen on the fiber surfaces and it is proposed that carbon monoxide reacts with carbon in the fiber to make these species.
