摘要

The presence of Li₂Si₂O₅ and LiAlSi₄O₁₀ could effectively improve the elastic modulus and transmittance of lithium disilicate(LD) glass-ceramics. Through synergistically modulation of the crystal content and grain size, we obtained high strength and high transmittance of LD glass-ceramics. The optimal sample had a high transmittance of 90.3%, the hardness was 7.72 GPa, the fracture toughness was 1.07 MPa·m^1/2, and the elastic modulus was 103.1 GPa.
