Summary

The nature and effect of silica coatings which develop on Nicalon™ ceramic fiber surfaces upon exposure to O2He gas mixtures at 1400°C was investigated. Heat treated samples were analyzed for their chemical composition and bonding of the elements present both on the surface and in the bulk of the fiber. Changes in the fiber weight, density and tensile strength retention are used to explain the reaction behavior. One goal of the study was to determine the potential of a silica layer as an effective interfacial diffusion barrier which would provide good retention of mechanical properties to Nicalon™ ceramic fibers after thermal exposure.
