[ES] Son objeto de la invención vidrios bioactivos, y sus usos, que comprenden óxido de boro y que presentan una sustitución de enlaces B-O en la estructura debida a la formación de enlaces B-N originada por nitruración. Preferentemente, dichos vidrios comprenden adicionalmente otros óxidos, tales como los incluidos, y así preferentemente ordenados conforme a su porcentaje molar y de mayor a menor, en la secuencia SiO2 > CaO > Na2O > K2O > B2)O{sub,3 > P(sub,2)O5. La presente invención también se refiere a procedimientos de obtención de vidrios bioactivos nitrurados que comprenden la mezcla de polvos vítreos que comprenden óxido de boro y, en su caso, óxidos adicionales, y la nitruración de dicha mezcla. Asimismo, son objeto de la invención andamiajes nitrurados que comprenden dichos vidrios bioactivos, procedimientos de preparación de los mismos, y aplicaciones de los mismos.
[EN] The invention relates to bio-active glasses and the uses thereof, said glasses comprising boron oxide, and having a substitution of bonds B-0 in the structure due to the formation of bonds B-N caused by nitriding. The glasses preferably also comprise other oxides, such as those included, and preferably ordered according to their molar percentage and from largest to smallest, in the sequence SiO2 > CaO > Na2O > K2O > B2O3 > P2O5. The invention also relates to methods for producing nitrided bio-active glasses, comprising: the mixing of glass powders containing boron oxide and additional oxides where appropriate; and the nitriding of said mixture. The invention further relates to nitrided scaffolds comprising said bio-active glasses, to preparation methods thereof, and to uses thereof.
