• Essential auxiliary materials used as lining for ferrous and non-ferrous metals and alloys furnaces are refractories.

• For Refractories and High-Temperature Ceramics

Refractories are rocks, minerals and their mixtures with the fusion temperature of over 1500^ОС that do not interact with molten metals. Detectable elements in various types of refractories are Mg, Na, Al, Si, K, Ca, Ti, Cr, Fe, Zr. Requirements to methods for detection of these elements in these refractories are described in the standard [GOST 2642.0-86. Refractories and refractory raw material. General requirements to analysis methods.]. All these elements may be determined with spectrometer BRA-135 according to the procedure similar to procedure of rock silicate analysis method.

Currently the Russian Federation standard for X-ray fluorescence of refractory materials and high-temperature ceramics GOST R “Refractories. X-ray fluorescence analysis", which is a translation of the international standard [ISO 12677:2003 Chemical analysis of refractory products by X-ray fluorescence (XRF) – Fused cast bead method] is being developed. The goal of Russian Federation’s national standard development is direct application of international standard ISO 12677, with due regard of specific features of refractories X-ray fluorescence analysis in the Russian Federation. The standard allows for detecting contents of Na₂O, MgO, Al₂O₃, SiO₂, P₂O₅, SO₃, K₂O, CaO, TiO₂, Cr₂O₃, Mn₃O₄, Fe₂O₃, Co₃O₄, NiO, ZrO₂, WO₃, BaO, SrO, HfO2, Y₂O₃, CeO₂, La₂O₃, SnO₂ within the range of 0.01% to 100%.

With specific features of Russian enterprises taken into account, this standard allows both the analysis of powder samples and sample preparation through fusion with lithium pyroborate, and concentration ranges of some elements have been changed. Analysis reproducibility and precision is better for fused samples, but analysis of compacted powder samples is allowed on most cases as well.
