PIXE-RBS analysis on potteries unearthed from Lijiaba Site

Analysis of elemental composition of porcelains unearthed from Waguantan kiln site by PIXE–RBS

“…The Table 2 were obtained after the removal of loss on ignition (L.O.I., i.e., CO 2 , crystallized H 2 O + , etc.) [9]. The experimental values and the certified values are in good agreement.…”

“…The method for factor extraction was principal component analysis, and the method utilized for rotation was quartimax with Kaiser normalization [9]. Tables 4 and 5 display the factor loadings for the factor analysis of each trace element in the bodies and glazes, respectively.…”

“…For this measurement, we needed to know the solid angle of the Au(Si) detector. The same method as in the paper of Wu et al [9] was applied to determine the solid angle, i.e., performing an RBS measurement for a 9 lm-thick Mylar film with an approximately 2 lm-thick copper layer deposited on it by magnetron sputtering.…”

“…Therefore, similar to other related archaeological research [9,13], the factor analysis method based on the multivariate statistical software SPSS [14] was used to address the measured elemental compositions and then compare the results [9]. Factor analysis is a widely used descending dimension method wherein the intrinsic relationships among multiple variables are analyzed, and a few of the factors are extracted to reflect the main information represented by the original multiple variables.…”

“…In this paper, the factor analysis was carried out for the major elements as oxides (MgO, Al 2 O 3 , SiO 2 , P 2 O 5 , K 2 O, CaO, TiO 2 , MnO, Fe 2 O 3 ) and trace elements (Ni, Cu, Zn, Rb, Sr, Y, Zr). According to the score of each factor for each sample, the similarities and dissimilarities in the elemental compositions of each sample could be compared easily [9].…”
