Gelcasting of Ferroelectric Ceramics: Doping Effect and Further Development

Processing and Properties of Zirconia-Toughened Alumina Prepared by Gelcasting

Zirconia-toughened alumina (ZTA) using yttria-stabilised zirconia is a good option for ceramic-ceramic bearing couples for hip joint replacement. Gelcasting is a colloidal processing technique capable of producing complex products with a range of dimensions and materials by a relatively low-cost production process. Using gelcasting, ZTA samples were prepared, optimising the stages of fabricatio...

Titanium with controllable pore fractions by thermoreversible gelcasting of TiH2

Thermoreversible gelcasting, a near-net-shape processing technique, is demonstrated here for titanium. The gelcasting system is composed of TiH2 particles suspended in a triblock copolymer gel that behaves as a viscous liquid above 56 C and an elastic solid at room temperature, a temperature-dependent transition that is fully reversible when solvent is present. Organic pyrolysis to remove the g...

Size optimization of silver nanoparticles synthesized by gelcasting using the Taguchi method

In the present study, silver nanoparticles were synthesized by decomposition of AgNO3 via gelcasting. Methacrylamide was used as a low toxic monomer for gel formation. Effect of monomer content (MAM), cross-linker to monomer ratio (MBAM/MAM), silver salt to monomer ratio (AgNO3/MAM), duration of calcination, and temperature of calcination were investigated to optimize the size of nanoparticles....

Preparation of porous porous bodies by gelcasting method and the analysis of its properties using the response surface method to remove methylene blue from aqueous solution

Zeolite were formed through agar gelcasting method.Response surface methodology ( RSM ) is proposed as a tool for rapidly optimizing the activation parameters in order to obtain the highest porosity of samples. 40 % of zeolite and 1 wt %  of agar was selected as optimal conditions. porous bodies with an optimal combination of 54.4% porosity , density 0.9 g / cm3 , and compressive strength of 6....
