- 中文摘要: Several silicate-containing dental ceramic glasses with the composition xMOy-zAl2O3-SiO2 (M = Na, K, Ca, Ba) were studied. The cations Ca+2, Ba+2, and Na+ were used to replace K+ in the glass structures. Under a hydrolytic resistance test according to ISO standards, some of these ceramic glasses had weight loss of less than 0.05%, which indicates a 30-year life span for dental applications in the oral environment. Hydrated ceramic glasses were found to have better mechanical properties than glasses without hydration, with approximately 20% greater flexural strength. Possible strengthening mechanisms for the hydrated ceramic glasses are explained. Furthermore, the powder preparation, microstructure, and hydration behaviors of these dental ceramics are discussed.
