摘要： Disclosed herein are glass-ceramic articles including a crystalline phase comprising a jeffbenite crystalline structure. The glass-ceramic articles may include a first surface, a second surface opposite the first surface, and a perimeter defining a shape of the glass-ceramic article. The glass-ceramic articles may further include a phase assemblage comprising one or more crystalline phases and a glass phase. The one or more crystalline phases may include a crystalline phase having the jeffbenite crystalline structure.

摘要： To provide a crystallized glass having high strength, a high transmittance, and high impact resistance. A crystallized glass according to the present invention includes a compression stress layer formed by ion exchange, in which the crystallized glass contains, as a composition, in mol%, from 50% to 80% of SiO2, from 0% to 4.8% of Al2O3, from 0.2% to 15% of P2O5, from 1.5% to 30% of Li2O, from 0% to 15% of Na2O, and from 1.5% to 10% of ZrO2, and the crystallized glass has a portion in which a Na ion concentration decreases from a surface side to an inner side of the glass.

摘要： A glass composition is provided that includes SiO2 in an amount from 50.0 to 65.0 % by weight; Al2O3 in an amount from 18.0 to 23.0% by weight; CaO in an amount from 1 to 8.5% by weight; MgO in an amount from 9.0 to 14.0% by weight; Na2O in an amount from 0.0 to 1.0% by weight; K2O in an amount from 0.0 to 1.0% by weight; Li2O in an amount from 0.1 to 4.0% by weight; TiO2 in an amount from 0.0 to 2.5% by weight,Y2O3 in an amount from 0 to 10.0 % by weight; La2O3 in an amount from 0 to 10.0 % by weight; CezOs in an amount from 0 to 5.0 % by weight; and Sc2O3 in an amount from 0 to 5.0 % by weight. Glass fibers formed from the inventive composition may be used in applications that require high stiffness and have elastic modulus between 88 and 115 GPa. Such applications include woven fabrics for use in forming wind turbine blades and aerospace structures.
