Rheological properties of PZT suspensions for stereolithography

Physico-Chemical Study of Coating Formulation Based on Natural Apatite for the Elaboration of Microfiltration Membrane

“…As expected, a rise of temperature leads to a decrease of the suspension viscosity (Figs. 2a and 3a.) according to an exponential relationship (Law of Arrhenius) whose expression is given by [22]:…”

Highly loaded UV curable nanosilica dispersions for rapid prototyping applications

“…[5] authors present curing of dispersions containing alumina and zircon, other include PZT in Ref. [6], BaTiO 3 7 or micrometer size silica. 8 These form the base of our research which pertains to the possibility of nanosilica dispersions in acrylates and their UV curability.…”

High solids loading ceramic colloidal dispersions in UV curable media via comb-polyelectrolyte surfactants

“…Stereolithography relies on relatively UV transparent dispersions having viscosities lower than 5 Pa s (30 1/s) [1]. Numerous studies of dispersions of micrometer and submicrometer powders in organic and aqueous media have been made [1][2][3][4][5][6][7][8][9]. Organic systems are advantageous due to the wide choice of monomers and oligomers for composite formulation and fast curing.…”

“…Nanometer and submicrometer ceramic particles are advantageous for high resolution microstructures, surface quality and reduced sintering temperatures. Although few particle types can be efficiently dispersed in organic UV curable monomer mixtures [10], special surfactants are frequently needed to increase particle solids loading to the levels required for ceramic processing (>40 vol%) [2,[4][5][6][7][8][9].…”
