Abstract

A novel, two step process for synthesis of Al2O3 microtubes from short carbon fibers as templates is reported. In the first process step, the carbon fibers are coated with a Al-AlN-Al4C3 composite in a microwave plasma fluidized bed CVD process. The coated material is then being treated in a furnace on high temperature in air, resulting finaly with alumina microtubes (hollow fibers).
