Since the 1990s, the automotive industry has become the largest consumer of platinum (Pt), palladium (Pd), and rhodium (Rh) on account of the arrival of catalytic converters in car exhaust systems. Approximately 40% of the total Pt, 74% of the total Pd and 80% of the total Rh were consumed by the auto catalyst industry in 2012.

As it has been previously demonstrated[1], borate fusion using an M4TM gas instrument, coupled with Wavelength Dispersive XRF, has the qualities needed to comply with the analytical targets described in both the ASTM C 114[2] and the ISO/DIS 29581-2[3]. As the demand for electric fusion devices increases in the cement industry, it is of interest to evaluate the performance of the LeNeo electric fusion instrument to assess its capacity to comply with these analytical standard test methods using the same calibration strategy. .

The analysis and determination of metals and trace metals in high silica and alumino-silicate samples such as catalysts and Zeolites are never easy, mainly because of the dissolution process. Samples containing silica often need hazardous chemicals (HF), strong acids (HClO4 ) or microwave digestions.

Sand is mostly used as a raw material in the production of many industrial products such as glass and cement, while aluminosilicates are used in the building, refractory and catalyst industry. It is important to know the exact compound concentrations of these materials so they remain within the tolerances over time and ensure the constant quality of final products. By knowing the exact concentration of raw materials to use for the creation of final products, you avoid waste and save costs.

This application note describes the texture analysis of a rolled copper specimen. The experimental data were measured on a multi-purpose X-ray diffraction system equipped with a texture cradle.. In polycrystalline solid materials, such as a wide class of metals and ceramics, usually the orientation of the crystallites, constituting the matrial, is not distributed randomly, like in an ideal powder specimen. In most cases a preferred orientation of the crystallites with respect to the sample reference frame is present. In materials science this preferred orientation is referred to as texture. .
