结果表明:AIN与SiO2-B2O3-ZnO-Bi2O3系玻璃在950℃能够很好地烧结。该陶瓷的性能取决于烧结体的致密度和玻璃含量,当w(玻璃)为40%-60%时,陶瓷具有较低的εr(3.5-4.8)和tan δ[(0.13-0-48)×10^-2]、较高的λ[5.1-9.3W/(m·K)]以及与Si相接近的α1[(2.6-2.8)×10^-6·K^-1],适用于低温共...
A glass filler of 60Bi 2 O 3 -20B 2 O 3 -10SiO 2 -5ZnO-5Al 2 O 3 (mol%) was utilized to join 99Al 2 O 3 ceramic and Al alloy 1060 at low temperature, which effectively addressed the negative impact caused by the indelible oxide film on the aluminum surface during the ...
THERMAL-PROPERTIESLow melting point glass systems were explored as candidates for binders of solid oxide nuclear wastes which include volatile elements such as radioactive iodine. The base glass systems considered were ZnO-Bi2O3-B2O3 and ZnO-Bi2O3-SiO2, with specific compositions selected for ...
The Bi2O3 content has a strong effect on the glass transition temperature (Tg) and glass structure. The contact interface is tailored by transmission electron microscopy. For low Tg glass frits, the SiNx layer is decomposed and oxidized, forming a SiO2 layer. Both globules and inverted ...
