Contact phenomena and interactions in the system SiC-SiO2-R x O y in condensed matter

Densification, Crystallization, and Dielectric Properties of AlN,BN, and Si3N4 Filler‐Containing LTCC Materials

“…The BN30 sample (having more glass) showed that earlier densification started at~670°C, but a limited change of~3.7% only up to~750°C. 15,16 The gaseous products are reported to depend on glass chemistry since they are the by-products of certain chemical reactions at specific temperatures. It is assumed that the glass has difficulty in wetting surfaces of the BN particles, which is required for the initial sintering of glass-driven densification.…”

Chemically Driven Zero Shrinkage Dielectric Ceramics

“…Yurkov et al . investigated the interactions between SiC and a molten glass (SiO 2 –B 2 O 3 –K 2 O glass) at >1150°C, as the “bubbling” phenomenon that was obviously observed depending on processing condition . Mailliart et al .…”

Selection criteria for sealing glasses for SiC packaging

“…Alumino borosilicates [5][6][7][8]22], soda-lime silicates [23], silicates [9] and glasses of the Pyrex type [5,6] have been shown to react in contact with SiC at temperatures above 1420 K to produce bubbles. All of the observations by other groups are consistent with the thermodynamic predictions given here.…”

“…Aluminosilicate glasses with MgO [1][2][3], Y 2 O 3 [4], aluminoborosilicate glasses [5,6], zinc borate glass [7], borosilicate glass [8,9] have been used as well as glass-ceramics [10,11]. Approximate chemical compositions of glasses do not constitute an adequate guide to their sealing properties.…”
