| description | The invention provides toughened glass ceramic with high strength and application thereof. The toughened glass ceramic comprises a main crystal phase (Zn, Mg) Al2O4 crystal phase and a secondary crystal phase tetragonal ZrO2 crystal phase. The strengthened glass ceramic includes a compressive stress layer region extending from a surface of the strengthened glass ceramic to a depth of compression, and has a tensile stress layer region inside the strengthened glass ceramic. The compressive stress layer depth DOL0 of the toughened glass ceramic is greater than or equal to 0.21 t, t is the thickness of the toughened glass ceramic, | CTAV | is greater than or equal to 70 MPa, and the toughened glass ceramic is endowed with a specific stress structure by meeting the DOL0 and | CTAV |, so that the toughened glass ceramic has excellent drop impact resistance and high mechanical strength.
