Nanocrystalline Mullite Synthesis at a Low Temperature: Effect of Copper Ions
Nanocrystalline mullite with grain sizes in the range of 13-30 nm has been prepared by the sol-gel route at a temperature as low as 600 degrees C with the incorporation of copper ions as copper sulfate. Characterization of the copper-doped mullite was performed by DTA-TG, X-ray diffraction (XRD), FESEM, and FTIR spectroscopy.
