Abstract

Vitrocéramique obtenue en cristallisant in situ, de façon réglée, un corps de verre. Le verre contient, en poids, 40 à 85 % de SiO2 , 2,5 à 17 % de N, ces deux corps formant au moins 40 % du poids de la composition, et au moins 15 % de formateurs ou modificateurs de réseau Mx Oy , constitué par un au moins des oxydes suivants : oxydes de métaux alcalins, oxydes des éléments des groupes IIA et IIB de la classification périodique, B2 O 3 et Al 2 O3 . Application à la fabrication d'articles en vitrocéramique.
