Abstract
Abstract A (1+2) barium carbonate-boric acid flux mixture used in a 10:1 fluxsample weight ratio is effective in decomposing a wide variety of high alumina, zirconia, and magnesia refractories. Among the advantages demonstrated are its low flame background, minimal matrix effects, freedom from impurities and its capability for use in determination of trace levels (100 p.p.m. or less) of all the alkali and most of the alkaline earth metals.
