The activity of the quality control and research and development laboratory allows to maintain a high attention on products ensuring compliance with specifications and trying to intercept customer expectations by focusing on product innovation. The presence of qualified personnel and specialized instrumentation allows you to always face the most suitable choices to meet the demands of even the most demanding customers. Chemical analyses, for example, by X-ray spectroscopy are the basis for the assessment of refractory properties of intermediate and finished products, but the quality chain begins with the accurate evaluation of raw materials such as coal whose characteristics are carefully studied through thermo-gravimetry. Last but not least a cutting-edge technique used for the dimensional characterization of granulated solids is laser particle size.
