Summary

Celsian (BaO·Al2O3·2Si02) is an attractive matrix material for ceramic composites used in high-temperature structural applications. In the present contribution, near net-shaped, phase-pure celsian bodies were prepared by the oxidation of solid, shaped Ba-Al-Si precursors at temperatures ≤ 1260°C. Celsian-matrix composites, reinforced with alumina particulates and with aluminosilicate fibers, were also produced by the oxidation of metal/oxide precursors at peak temperatures ≤ 1260°C. X-ray diffraction and electron microprobe analyses were used to examine the precursors after various stages of oxidation. The phase evolution leading to celsian is discussed.
