XRF is used for routine quality assurance of production in many branches of industry. For example, in the iron and steel, the manufacture of cement, the animal feed and fertiliser, the refractories industry and in all fields of metal processing. Thanks to its high degree of precision, the analysis of samples which have been homogenized by a fusion process is becoming increasingly important.
The excellent stability of platinum – even in the 1100 – 1200°C temperature range – is further improved by the addition of 5% gold. This alloy has higher strength and, in particular when melting silicates, a low wettability so that the melt can be easily removed from the crucibles and casting dishes.
