Abstract: Fe₂O₃ content controls the microstructure (porosity, pore size, grain size) and correspondingly an evolution of the light transmittance of gel monoliths based on boehmite. Porosity decreases with Fe₂O₃ content and it is completely eliminated in samples containing 6 mass % Fe₂O₃. Resulting polycrystalline material becomes thus transparent at temperatures as low as 1250°C.
