In terms of silica surfaces, what does "hardly loaded" mean? Andreas Kröger: Because of the intense thermal treatment, the surfaces of the SIO2 particles are briefly stressed. However, their surface properties are not adversely affected. Furthermore, combustion-derived residues are not incorporated, which would negatively influence the final formulation. What are the dimensions of the hot gas reactor and what batch quantities can it contain? Lars Leidolph: APPtec technology is a continuous process for the production and/or modification of powder materials. The combined test and production plant in our Technology Center in Weimar has a capacity of 200-500 tons ...
