Abstract
The application discloses a preparation method and application of high-performance transparent microcrystalline glass and belongs to the technical field of microcrystalline glass materials. The raw materials include the following proportions in terms of oxide molar percentage: SiO243%-54%, MgO 24%-34%, Al2O36.5%-12%, Li2O 0.5%-4%, Na2O 1.5%-13%, K2O 0-2%, Ga2O30-1.5%, P2O50.1%-1.2%, TiO23%-5.5% and Ta2O50-0.4%. The microcrystalline glass prepared through melting, forming, annealing and two-step controlled crystallization has a transmittance of more than 75% under the condition of a thickness of 0.7 mm and a wavelength of 550 nm, has excellent hardness and an elastic modulus, and can be used for electronic device transparent protection components, optical windows, industrial observation windows and high-strength transparent structural members.
