Abstract: A high-hardness transparent glass ceramic and a preparation method therefor, wherein the components by weight percentage include: 55.0%-70.0% of SiO2, 15.0%-20.0% of Al2O3, 0%-10.0% of MgO, and 0%-12.5% of ZnO, necessarily including one of MgO or ZnO, and the crystallized glass thereof contains microcrystals of spinel crystal. In the present invention, a suitable precursor glass is subjected to thermal treatment, and microcrystals are separated from the glass substrate by crystallization, producing a glass ceramic having a Moh's hardness greater than 7 and a visible-light transparency rate greater than 80% through 1 mm of the glass. The glass ceramic of the invention overcomes the problem that ordinary optical glass is easy to be scratched. The present glass ceramic can be served as protective face for mobile phones, protective glass for optical instruments and in communications equipment, substrate for magnetic disks, LCD panel, or protective glass for other optoelectronic devices.

Abstract: An internally nucleated, toughened cordierite glass-ceramic is disclosed. The cordierite glass-ceramic has good oxidation resistance and fracture toughness and coefficient of thermal expansion rivaling that of silicon nitride. The glass-ceramic may be cast as a liquid. Annealing produces a material of high crystallinity combining high hardness, high Young's modulus, good thermal stability, high strength, low density and good dielectric properties. The glass-ceramic comprises interlocking crystalline phases dominated by cordierite and a second phase having an elongated or acicular structure. A third phase may comprise a crystalline ceramic that promotes acicularity of the second phase. The third phase is preferably capable of twinning.
