  2. 1. Water-based Tape Casting of Ceramics and Fabrication of Ceramic Laminates

    Author : Annika Kristoffersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water-based tape casting; latex binders; high solids loading; silicon carbide; colloidal stability; polyelectrolyte dispersants; alumina; ceramic laminates; rheology;

    Abstract : The objective of the work presented in this dissertation has been twofold: to develop a water-based system for tape casting and to build laminar structures from the tapes. A set of requirements on the binder was specified and latexes were identified as suitable for water-based tape casting, mainly owing to their low viscosity and high polymeric content. READ MORE

    Abstract : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. READ MORE
