Title (EN) DURABLE TUNGSTEN-DOPED TIN-FLUOROPHOSPHATE GLASSES
(FR) VERRES DE FLUOROPHOSPHATE D'ETAIN DURABLES DOPES AU TUNGSTENE
Abstract: front page image
(EN)Tungsten-doped tin-fluorophosphate glasses are described herein which exhibit excellent humidity resistance, thermal resistance, and have a low glass transition temperature which makes them suitable for low temperature sealing applications, such as for encapsulating electronic components. In one embodiment, these glasses comprise 55-75 % Sn, 4-14 % P, 6-24 % O, 4-22 % F, and 0.15-15 % W on a weight percent elemental basis.
(FR)L'invention concerne des verres de fluorophosphate d'étain dopés au tungstène, présentant d'excellentes résistance à l'humidité et résistance thermique, ainsi qu'une température de transition vitreuse basse permettant de les utiliser dans des applications de scellement à basses températures, telles que l'encapsulation de composants électroniques. Dans un mode de réalisation, ces verres contiennent 55-75 % de Sn, 4-14 % de P, 6-24 % d'O, 4-22 % de F et 0,15-15 % de W, en pourcentage en poids élémentaire.
