Abstract
Methods have been developed for analysis of alumino-silicate and
magnesia-chrome materials by X-ray fluorescence by fusing the
materials into a glass disc and then analyzing the components by
irradiating with X-rays. Lithium tetraborate has been used for
alumino-silicates, and sodium hexametaphosphate along with
lithium metaborate has been used for chrome-magnesia materials.
Addition of La20 3 as a heavy absorber has been eliminated in both
cases by using programmes for inter-elemental corrections by the
computer. Calibration lines made from available standards have
been made and their standard deviation and coelfcient of determinations
are mentioned. To cope with the changes in refractory technology,
thermal analysis equipment have been used to solve problems
related to change in thermal applications. DT A and TGA have
been used extensively and some specific applications have been
mentioned. The use of GC, GCjMS and HPLC are also becoming
common to characterize health and safety related problems.
