PROCESSING AND CHARACTERIZATION OF TUBULAR CERAMIC SUPPORT FOR MICROFILTRATION MEMBRANE PREPARED FROM PYROPHYLLITE CLAY [PDF]

open access: yes, 2011
Tubular macroporous support for ceramic microfiltration membranes were prepared by extrusion followed by sintering of the low cost pyrophyllite clay. Clay powders mixed with some organic additives can be extruded to form a porous tubular support.

Firing transformations of an argentinean calcareous commercial clay [PDF]

open access: yes, 2013
Mineralogical transformations caused by firing are usually studied by XRD methods only semi-quantitatively. In this work the original mineral disappearance and the neo-mineralization were evaluated quantitatively.

A new route of synthesis of Na-Mica-4 from sodalite [PDF]

open access: yes, 2014
Synthesis of Na-Mica-4 has been achieved by a ``mix and calcine¿¿ method using sodalite and magnesium fluoride as the only precursors. Previous research found sodalite as a key intermediate reaction product in the formation of Na-Mica-4 when the NaCl ...

Alkali-etched heated clay: Microstructure and physical/mechanical properties

open access: yesJournal of Asian Ceramic Societies, 2016
The microstructure of alkali-etched heated kaolinitic-illitic clay, which was cured in wet atmosphere at different temperatures and times, was investigated by using X-ray diffraction, Fourier-transform infrared spectroscopy, thermal analysis and scanning

Zeolite-feldspar epiclastic rocks as flux in ceramic tile manufacturing [PDF]

open access: yes, 2007
Low-cost, naturally-occurring mixtures of feldspar and zeolite occurring in epiclastic rocks are promising substitutes for conventional quartz-feldspathic fluxes in ceramic bodies, since their fusibility and low hardness are expected to improve both ...
