Gelcasting of aluminum titanate. Final report [PDF]

, 1997
This Cooperative Research and Development Agreement (CRADA) was undertaken to assess the applicability of the gelcasting process for forming automotive exhaust port liner green bodies using Golden Technologies` proprietary aluminum titanate powder composition. A gelcasting process, specifically tailored to Golden Technologies` powder, was developed and

Porous Si3N4 Ceramics Prepared by Gelcasting Route and Pressureless Sintering at Different Temperatures

Materials Research
In this work, the gelcasting method was used to prepare porous Si3N4 ceramics, using sodium lauryl sulfate and Isobam 110 as foaming and gelling agents, respectively. Samples sintered at different temperatures were characterized by mercury porosimetry, X-

Gelcasting of alumina

, 2005
Ispitan je savremeni postupak oblikovanja keramičkih prahova, "livenje geliranjem", eng. gelcasting, zasnovan na konceptima polimerne hemije i klasičnog postupka livenja. Postupak obuhvata livenje stabilne suspenzije pripremljene sa velikom količinom čvrste faze (keramički ili metalni prah) i rastvorom organskih monomera, monofunkcionalnog i ...

Effect of TMAH on the rheological behavior of alumina slurries for gelcasting

Journal of Asian Ceramic Societies, 2017
Tetramethyl ammonium hydroxide (TMAH) has been demonstrated to increase solids loading effectively and to accelerate gelling rate of alumina slurries gelled by Isobam (a copolymer of isobutylene and maleic anhydride) system.

Effect of emulsion composition on gel strength and porosity in the preparation of macroporous alumina ceramics by freeze gelcasting

Journal of Asian Ceramic Societies, 2015
The freeze gelcasting of hydrogenated vegetable oil-in-aqueous alumina slurry (HVO-in-AAS) emulsions of HVO to AAS volume ratios in the range of 1.34–2.69 prepared from slurries of various alumina concentrations were studied to prepare macroporous ...

Procesamiento cerámico de β-TCP para la fabricación de piezas implantables

Boletín de la Sociedad Española de Cerámica y Vidrio, 2006
This work describes a method for obtaining large-scale productions of β-TCP by mass-precipitation from calcium and phosphate solutions. The setting of the synthesis conditions was made by studying operational parameters like the concentrations of the ...
