Wilson (1990) has provided some details of the microstructural evolution in this fiber. A fine-grained o-AljOj fiber is obtained by seeding the high temperature a-alumina with a very fine hydrous colloidal iron oxide. The fine iron oxide improves the nucleation rate of a-Al Oj, with the result that a high density, ultra-fine, homogeneous o-Al203 fiber is obtained. The rationale for seeding with iron oxide as follows. Basic salts of aluminiun decompose into transition aluminum oxide spinels such as above 400°C. These transition cubic spinels... [Pg.145]

A key characteristic of the polymer-derived SiC fibers is their ultra-fine microstructure with grain sizes in the nanometer range. Fine grains are typically required for good... [Pg.34]
