Mineral fillers are indispensable in many industrial branches and are used in a variety of different materials. In plastic technology they act as a classic extender to lower the costs of the production process but also as “active fillers” to improve the mechanical and optical property profile. In the paper industry, fillers are also used to reduce raw material costs and to adjust the optical as well as surface properties. However, fillers entail the problem that their application quantity is sharply limited. Inorganic fillers show no binding properties. They reduce the product strength with higher use and lead to complications in the further processing of the products (e.g. increased dust propensity during the packaging and printing processes). In order to expand the use of fillers and their positive effects on varying products and to prevent the negative effects of the material in parallel, mineralized cellulosic structures should be created for versatile applications in different branches of industry.
