Universal fusion technique

With sodium tetraborate fusions, small additions of oxidising materials (Na202, NaN03) have been found successful for substances that are difficult to fuse. 

Through calibration and re-calibration techniques possible interelement effects or influences from the matrix can be largely eliminated. Because of its worldwide importance the introduction of standard methods by atomic absorption started first with iron ores [67] and refractories. The ISO/TC 102 is presently occupied with draft proposals for the atomic absorption determinations of Na/K Ca/Mg, Zn, V, Pb and Al.

For almost all types of steel there is a similar problem in the dissolution step. Three elements, Al, Si, and W, behave differently in the analysis of the total content and require special methods. These methods are simple extensions of the technique, which in the case of the determination of acid soluble Al or Si, can simply be omitted. When, during the dissolution, an oxide residue remains, which in general consists of Si02 or A1203, this must be brought into solution with a fusion, and added to the rest of the sample. If the W concentration is higher than 0.5%, the dissolving acid solution should also include phosphoric acid. Thus, it is possible to produce a universal method for the elements that are contained in steel and which influence its properties.

Alvarez, Lius W. (1911-1988) A physicist and inventor bom in San Francisco, Alvarez was associated with the University of California, Berkeley, for many years. He explored cosmic rays, fusion, and other aspects of nuclear reaction. He invented time-of-flight techniques and conducted research into nuclear magnetic resonance for which he was awarded the 1968 Nobel Prize in Physics. He contributed to radar research and particle accelerators, worked on the Manhattan Project, developed the ground-controlled approach for landing airplanes, and proposed the theory that dinosaurs were rendered extinct by a massive meteor impacting Earth.
