Phase compositions of self reinforcement Al<inf>2</inf>O <inf>3</inf>/CaAl<inf>12</inf>O<inf>19</inf> composite using X-ray diffraction data and rietveld technique
MetadataShow full item record
The analysis of x-ray diffraction (XRD) patterns by the Rietveld technique was tested to the quantitatively phase compositions of self reinforcement Al2O3/CaAl12O19 composite. Room-temperature XRD patterns revealed that a-Al2O3 was the only phase presence in the CA0 sample, whereas the a-Al 2O3 and CaAl12O19 phases were found for CA5, CA15, CA30, and CA50 samples. The peak intensity of CA6 in the self reinforcement Al2O3/CaAl12O 19 composites increased in proportion with increase in CaAl 12O19 content in contrast to a-Al2O 3. The diffraction patterns for CA100 sample shows minor traces of a-Al2O3 even in relatively low peak intensity. It is suggesting that the in-situ reaction sintering of raw materials were not react completely to form 100 wt% CaAl12O19 at temperature 1650°C. Quantitative phase compositions of self reinforcement Al 2O3/CaAl12O19 composites by Rietveld analysis with XRD data has been well demonstrated. The results showed that the GOF values are relatively low and the fluctuation in the difference plots shows a reasonable fit between the observed and the calculated plot. © 2008 American Institute of Physics.
