摘要

An opaque gahnite-spinel glass ceramic is provided. The glass ceramic includes a first crystal phase including (Mg_xZn_1-_x)Al₂O₄ where x is less than 1 and a second crystal phase includes at least one of tetragonal ZrO₂, MgTa₂O₆, mullite, and cordierite. The glass ceramic has a Young's modulus greater than or equal to 90 GPa, and has a hardness greater than or equal to 7.5 GPa. The glass ceramic may be ion exchanged. Methods for producing the glass ceramic are also provided.
