· The XRD and XRF data of the calcined bauxite indicate that it is composed mainly of corundum (α-Al 2 O 3) which exists as mono-mineral phase and the alumina content is 85.39 with a lesser amount of silica reaching up to 7.20 . A high alumina batch of 76 alumina was prepared by mixing of 20 clay and 80 calcined bauxite.
Laboratory Analysis of Stardust Analytical Chemistry
· Single grain analysis has revealed a tremendous range of isotopic ratios (see Figures 2 and 3). It also led to the identification of new grain types such as corundum (Al 2 O 3) and spinel (MgAl 2 O 4) and silicon nitride (Si 3 N 4) as well as of rare subpopulations of SiC grains.

The field of quantitative phase analysis (QPA) from powder diffraction data is almost as old powder diffraction itself. Debye and Scherrer first developed the method around 1916 (Debye Scherrer 1916 1917) and between 1917 and 1925 Hull (1917 1919) and Navias (1925) were reporting studies of QPA related to the new technique.However further developments in QPA were relatively slow as much

fluorescence spectrometry (XRF) is a rapid and convenient method for nondestructive multi-elemental analysis. The detection range of XRF spans from part-per-million (ppm) fractions to major components. In particular the powder briquette method can be used to perform direct elemental analysis of the major and minor components of powder samples

· When corundum is chosen as an internal standard RIR i s values are known as I/I cor or RIR cor ( cor is denoted as the corundum ) (Hubbard and Snyder 1988 Hillier 2000). To obtain the RIR cor value a binary system composed of a corundum and a clay mineral is prepared and the mass ratio of the corundum and clay mineral is 1 1.
