THIN LI-AL-SI GLASS USED FOR THREE DIMENSION PRECISE MOLDING AND SUITABLE FOR STRENGTHENING

摘要

The present invention relates to a thin lithium-aluminosilicate glass for three dimensional precision molding and suitable for toughening, wherein after toughening, the glass has a center tension smaller than 50 Mpa, a surface compressive stress of 600-1200 Mpa, and a bending strength of up to 500 MPa. The glass also has a transition point lower than 550°C.
