Resumo: The PbO-SrO-B2O3 glass system with the of molar ratio of R (= PbO/B2O3) were prepared by fusion method. The elastic properties have been investigated using longitudinal and transversal ultrasonic wave velocity. Measurements were performed at room temperature and using pulse-echo technique at frequency of 5 MHz. The results indicate that, when increasing R value, the glass network stability decreases. This decrease indicates, of the increase the number of borate structures with non bridging oxygen (NBOs) at the expense of the decrease of borate units with tetrahedral structures. This feature may lead to the more open glass network structures and lower stiffness of the samples studied.

As propriedades elásticas tem sido investigadas a partir das medições das velocidades longitudinais e transversais das ondas ultrassônicas. As medidas foram realizadas a temperatura ambiente usando a técnica de pulso-eco a 5 MHz. Os resultados indicam que, com o aumento do valor de R, a estabilidade da rede do vidro diminui. A diminuição da estabilidade da rede vítrea indica o aumento do número de estruturas boratos com oxigênios não ligados às expensas da diminuição das unidades boratos com estruturas tetraédricas. Esta característica pode levar à ter no vidro estruturas mais abertas e a ter menor rigidez das amostras estudadas.Instituto Federal GoianoUniversidade Estadual Paulista “Júlio de Mesquita Filho”Universidade Estadual Paulista “Júlio de Mesquita Filho”IBRACON - Instituto Brasileiro do ConcretoInstituto Federal GoianoUniversidade Estadual Paulista (Unesp)Moya, Bianca ReisReis, Idalci Cruvinel DosReynoso, Victor Ciro Solano [UNESP]Barros, Mariana Da SilvaGomes, Kamila Ruthielle Silva2021-07-14T10:53:46Z2021-07-14T10:53:46Z2020-08-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article-application/pdfhttp://dx.doi.org/10.1590/S1983-41952020000400015Revista IBRACON de Estruturas e Materiais.
