Abstract | A laminate article comprises: (a) a core layer comprising a glass-ceramic composition, a first core surface, and a second core surface, the first core surface and the second core surface facing in generally opposite directions; (b) a first clad layer comprising a glass composition disposed on the first core surface of the core layer; and (c) a second clad layer comprising a glass composition disposed on the second core surface of the core layer; wherein (i) the core layer comprises a thickness within a range of from 150 µm to 200 µm; (ii) the core layer exhibits a coefficient of thermal expansion within a range from 2.5x10-5/°K to 4.5x10-5/°K; and (iii) the laminate article comprises an effective coefficient of thermal expansion within a range of from 8.0x10-6/°K to 2.0x10-5/°K. An electronic device incorporating the laminate article. A method of forming the laminate article.
L'invention concerne un article stratifié comprenant : (a) une couche centrale comprenant une composition vitrocéramique, une première surface centrale et une seconde surface centrale, la première surface centrale et la seconde surface centrale étant orientées dans des directions généralement opposées ; (b) une première couche de revêtement comprenant une composition de verre disposée sur la première surface centrale de la couche centrale ; et (c) une seconde couche de revêtement comprenant une composition de verre disposée sur la seconde surface centrale de la couche centrale ; (i) la couche centrale comprenant une épaisseur dans une plage de 150 µm à 200 µm ; (ii) la couche centrale présente un coefficient de dilatation thermique dans une plage de 2,5x10-5/°K à 4,5x10-5/°K ; et (iii) l'article stratifié comprend un coefficient effectif de dilatation thermique dans une plage de 8,0x10-6/°K à 2,0x10-5/°K. Un dispositif électronique incorporant l'article stratifié. L'invention concerne également un procédé de formation de l'article stratifié. |
