Sintering of glass matrix composites with small rigid inclusions

Enhanced thermal conductivity of low-temperature sintered borosilicate glass–AlN composites with β-Si3N4 whiskers

“…15 The CMBS glass used in this work can obtain various crystallized phases by designing the glass composition and controlling heat treatment process. 16,17 Furthermore, CaO and MgO are also being considered as effective sintering aids to AlN ceramics, 18 implying the good compatibility between the CMBS glass and AlN.…”

Structural, electrical and thermal properties of borosilicate glass–alumina composites

“…The sinterability of the composites decreases as the fraction of ceramic particles increases and it is promoted by the rising in temperature that enhances the glass viscous flow [39]. Accordingly, the densification results obtained in the present study demonstrate that when the composite samples were treated at the highest selected temperature, the borosilicate is much more softened and viscous flow occurs more easily because the glass-Al 2 O 3 composites are better densified.…”

“…In previous works related with the sintering of glasses and of glass matrix composites containing rigid inclusions [36][37][38][39], it has been shown that the predominant mechanism of densification is the viscous flow of the glass. The sinterability of the composites decreases as the fraction of ceramic particles increases and it is promoted by the rising in temperature that enhances the glass viscous flow [39].…”

Glass‐Ceramic Composites from Borosilicate Glass and Alumina‐Rich Residues

“…With the increase in Valoxy content from 10 to 30 wt%, the cristobalite peak was observed to decrease and it is almost absent (see Fig. It is known that above the softening temperature, BSG can form a reasonably low viscosity viscous fluid, 24 which should improve the wetting behavior of glass toward the included refractory particles, thus leading to better encapsulation of Valoxy particles in the glass matrix. At 950°C, a similar behavior was observed: In this case, www.ceramics.org/ACT Functional Glass-Ceramics E21 the cristobalite growth inhibition was observed from Valoxy concentration >10 wt% (Fig.…”
