Raw Materials

Wolframite, a solid solution of ferberite and hübnerite, is widely used for manufacturing electric filaments of light bulbs, armor-piercing ammunition, or hard tungsten carbide machine tools

Raw Materials

Sorting, identification, or assessment of raw materials

Each year, every person in Germany uses more than 16 tons of metal, concrete, wood and other raw materials. That adds up to 44 kilograms a day. By both European and international standards, Germany places high on the list of resource consumption.

This statistic was highlighted in a resource report from the German Federal Environmental Agency that was presented in November 2016 at the National Resource Forum in Berlin. As the transformation of global technology takes place, the demand for raw materials is essentially determined by the stage at which society is developing. Raw materials are an indispensable asset for the industrial value chain, technological progress and for maintaining our standard of living. For this reason, not only is the demand for raw materials on the rise; the demand for quality is growing as well. As know-how in fields such as materials technology increases, there is a growing reliance on specific raw materials for optimizing innovative high-performance materials.

Each raw material – depending on the intended processing method – is further developed into different material alloys or material composites. In this phase of the product life cycle, the demands placed on NDT are essentially characterized by the destruction-free analysis of raw materials. To this end, Fraunhofer IZFP engineers and researchers are developing application-oriented and customer-specific solutions for a faster and more precise characterization of the raw material properties, thus optimizing the industrial value chain while simultaneously making more efficient use of the resources.

Moreover, nondestructive monitoring methods are necessary for many industrial applications in order to analyze raw materials for impurities or the degree of purity in primary and secondary raw materials such as aluminum. As a result, Fraunhofer IZFP conducts future-oriented research and development activities into the methods, processes and systems required to characterize the material alloys and material compounds being used.

Given the limited availability of conventional raw materials, renewable raw materials (wood, cellulose, hemp, starch, etc.) are taking on even more importance. Nondestructive inspection processes play a vital role in ensuring and optimizing the quality and resource efficiency of renewable raw materials as well.
