摘要	YAG (Y(3)Al(5)O(12)) powder was prepared by co-precipitation method. To avoid pH values changing intensely during titration process, the NH(4)HCO(3) solution with NH(4)HCO(3) was used as precipitant solution. The pH change of precipitant solution during titration process, compositions of precursor, phase formation process and morphology of the prepared powder were investigated by means of pH meter, FT-IR, XRD and TEM. The results show that the presence of NH(4)HCO(3) in NH(4)HCO(3) solution is crucial to alleviate the pH change, lower the calcination temperature and meliorate the morphology of YAG powder. The mechanisms were studied in detail. The YAG phase can be obtained at a lower temperature of 900 degrees C. The obtained powder, composed of elliptical particles, showed a meliorated morphology.
