Ceramic papers containing Y zeolite for toluene removal
(Elsevier Science, 2011-11)
A papermaking technique with a dual polyelectrolyte retention system was used for the preparation of NaY zeolite-containing papers, which implied the use of cationic and anionic polymers. Two kinds of fibers were employed, ...
The use of FT-IR spectroscopy and SEM/EDS characterization of slips and pigments to determine the provenances of archaeological ceramics: The case of Guanacaste ceramics (Costa Rica)
(2021-03)
In this paper, the red and black pigments and slips of 63 Guanacaste ceramics were analyzed by Scanning Electronic Microscopy and infrared spectroscopy. All the pigment layers were made by dilution of a pure pigment in the ...
The correlation of vibration signal features in grinding of advanced ceramics
(2016-09-01)
Monitoring the grinding of ceramics using the vibration signal has been presented as an alternative for the diagnosis of the workpiece surface. This paper has the objective of studying the vibration signal through spectral ...
Enhancing Mechanical Properties of Ceramic Papers Loaded Whit Zeolites using Borate Compounds as Binder
(North Carolina State University, 2013-01)
NaY zeolite-containing ceramic papers were prepared by a papermaking technique with a dual polyelectrolyte retention system that implied the use of cationic and anionic polumers. To improve their mechanical properties, we ...
