## Abstract A commercial glass fiber with Al~2~O~3~ (68.4%) and SiO~2~ (27.6%) as major components and CaO, TiO~2~, Fe~2~O~3~, and CuO as minor components was used as substrate in a silica sol–gel coating process. After cleaning, fiber samples were immersed into tetraethoxysilane (TEOS) at room tem
Dense polycrystalline mullite was equilibrated for 6 h in air at 1800 • C and then quenched to room temperature. During subsequent annealing at 1600 • C a gradual decrease of the Al 2 O 3 concentration in the grains occurs which approaches an equilibrium concentration after about 100 h annealing tim
