Kinetic study of the transformation of sodalite to nepheline

Journal of the American Ceramic Society, Volume 105, Issue 6, Page 4336-4347, June 2022., 2022
Abstract The kinetics and mechanism of the development of nepheline (NaAlSiO4) through thermal transformation of sodalite (Na4Al3Si3O12Cl) was studied by means of differential thermal analysis at different heating rates (10°C min−1 to 50°C min−1) to control the evolution of the crystallization fraction.

Trial inspection of exterior‐tile wall specimens with a prototyped tile‐debonding diagnostic device

JAPAN ARCHITECTURAL REVIEW, Volume 4, Issue 1, Page 28-40, January 2021., 2021
The prototyped tile debonding diagnostic device has an impact force sensor and four microphones and outputs detection parameter RAF for each microphone. The maximum value of RAF at the four microphones was defined as RAF‐max. A threshold value of RAF‐max was set and the results of detection of debonding were displayed on figures of the specimens.

PROTECTIVE TREATMENTS FOR LAPPED PORCELAIN STONEWARE TILES AND EVALUATION OF THEIR CLEANABILITY [PDF]

Ceramics - Silikaty, 2017
Since the arrival of lapped porcelain stoneware tiles on the market, several studies have been focused on the improvement of the technical characteristics of the surfaces of these products. Surface lapping induces aesthetical improvements, but can at the same time deteriorate the performance of porcelain stoneware tiles. To overcome this problem, it is
