Abstract
The purpose of this project was twofold - to synthesize several
electron microprobe glass standards in the system: SiO2 - Al 2O 3 --
Cao -- MgO, and to utilize these standards in empirically calculating a
set of binary correlation coefficients for use in the Bence-Albee data
reduction method. Ten standards were prepared using the four end
member oxides in coarse, crystalline form as starting materials
(99.9+% purity). The careful synthesis and extensive analysis of the
standards insured that they are homogeneous with compositions known to
better than 5xl0- 4 oxide weight percent. The X-ray intensities measured
for Si, Al, Ca and Mg in the standards and the oxides, plus the known
compositions of the glasses provided the information necessary to
empirically derive the set of binary correlation coefficients ("alpha
factors") within the SiO2 - Al2O3 - CaO - MgO system.
