Abstract

Spinel and spinel-zirconia composite powder were synthesized by soft chemistry method using ［AlO4Al12(OH) 24(H2O) 12］7+（abbreviated Al13） as aluminum source. Precursor structure, reaction progress and material microstructure evolvement were characterized by 27Al NMR, XRD, DSC-TG and FTIR. Spinel precursor was prepared by mixing Al13 solution and magnesium slurry which was obtained by milling the mixture of MgCl2·6H2O and NaOH, and its component included Mg6Al2CO3(OH)16·4H2O and β-Al(OH)3. Spinel is formed from calcination of this spinel precursor at 600℃ for 1h, and only spinel is formed at even higher temperatures. Spinel-zirconia composite powder precursor is prepared by hydrolysis-precipitation process of Al13, MgCl2·6H2O and ZrOCl2·8H2O solution. Spinel-zirconia composite powder can also be obtained from calcination of the precursor at 600℃. FTIR spectra of the Al13 powder and spinelzirconia precursor show that the ［AlO6］ absorption band shifts from 608cm-1 to 601cm-1 and ［AlO4］ from 761cm-1 to 723cm-1.The result shows that Al13 has obvious advantage in synthesis of spinel and spinelzirconia composite powders at low temperature because Al-O-Mg bond can be formed easily in precursors.

Key words： Al13; spinel; spinel-zirconia; low temperature synthesize
