The current work has been established to study the devitrification kinetics of the silica glass prepared by gel-casting method. The ordinary rate and Avrami equations were used to calculate the ...

Abstract: The decrease in transmittance of annealed optical fiber has been measured versus temperature and time. The annealing loss is due to the devitrification of the glass and OH absorption in the ...

IN an article by Audley, published in the Transactions of the Ceramic Society, vol. xvi., part i., p. 124, it is stated that the addition of zirconia to fused quartz gives a product resembling ...

Although particular attention has been paid to responses of hydrocarbon storage and percolation capacity to the devitrification concerning lacustrine tuffaceous shale reservoirs in recent years, there ...

ABSTRACT: The crystal growth and nucleation in glasses in the lithium silicate system have been investigated. Phase separation in ultimately homogenized glasses of the lithium silicate system ...

Over time, some glasses experience an aging process or devitrification, in the latter of which the amorphous configuration settles into a more regular structure. In most cases, devitrification is ...
