A glass system containing B2O3, CaO, SiO2, P2O5, K2O, and TiO2 was fabricated and studied for its physical properties and elastic moduli. The results showed that the glass has good thermal stability and mechanical properties, making it suitable for applications such as dental prosthetics and orthopedic implants.
28B(2)O(3) - 15CaO - 14SiO(2) - 18P(2)O(5) - (25 - x) K2O - x TiO(2)x = (0 <= x <= 5 mol%) glass system was fabricated. XRD was used to verify the amorphousness of the glasses. The molar volume and density have been calculated. Differential thermal analysis was used to investigate the thermal stability of the fabricated glasses. The pulse-echo technique was used to measure ultrasonic velocities. The elastic moduli of the glasses, as well as all mechanical variables, were evaluated. The elastic moduli have been theoretically analyzed. The experimental data of elastic moduli were interpreted using the Bond compression and Makishima - Mackenzie models. Dental prosthetics and orthopedic implants are two examples of applications for these glasses.
