Use of FTIR reflectance spectroscopy to monitor corrosion mechanisms on glass surfaces

Influences of multiple firings and aging on surface roughness, strength and hardness of veneering ceramics for zirconia frameworks

“…A temperature of 200 8C was selected, higher than the 134 8C as specified in the standard. An earlier investigation showed that the effect of changes in temperature to be essentially the same as those of changing the time of exposure and that temperature did not substantially affect the mechanism of degradation of the glass surfaces, only the kinetics [39]. This showed that the process of aging from low temperatures to high may be the same as that of aging over time.…”

Impact of soda-lime borosilicate glass composition on water penetration and water structure at the first time of alteration

“…Most of the studies about the glass hydration were essentially performed on simplified [11,13,14], natural [15,16] or archeological [17] glasses. In this study, we have chosen soda-lime borosilicate glasses containing zirconium and having composition close to the French R7T7 reference nuclear glass which for the structure [18] and the alteration were already studied in details (dissolution rates and morphologies of the alteration layers at pH higher than 7) [19][20][21].…”

Effects of multiple firings on the microstructure of zirconia and veneering ceramics

“…The chemical property of ceramic materials, which consist mainly of various crystal phases, is affected by a variety of factors, such as the composition and microstructure of the ceramic materials, as well as temperature [10][11][12][13] . Firing protocols performed at high temperature (750-900°C) usually apply 2-5 successive firings in simple cases.…”
