,Am DTA orientiertes Qualitätsmodell,e weight loss was found to be proportional to the reaction time and to the thickness of the silica-rich layer which formed on the surface of the glass. During the second stage, the weight loss was found to slow down gradually, and the concentration of Na, Ca, Si, and P in the reacted solution increa

The additive cations in the grain boundary migrated to the surface oxide scale, and beneath the scale, the decrease of glass phase were observed.

Microdesigning of Ceramic-Metal Compositesl design are addressed with respect to capillarity and reaction thermodynamics. The B.C−Al system is used to illustrate the formation of tailored microstructures which exhibited average fracture strength of 621 MPa and fracture toughness of 9.7 MPa·m. at 36 v/o Al content.

Microstructure Characterization of Basalt Glass-Ceramicshe original glasses were taken, and scanning electron microscopy with energy-dispersive x-ray microanalysis was performed in order to characterize the microstructure. Potential applications of these basalt glass-ceramics are as wear-resistant materials and as a candidate matrix for nuclear-waste immobilization.
