Bioactive glass is widely recognized for its exceptional biocompatibility and bioactive behavior, particularly its ability to bond with bone. One of its primary applications is as a bone graft material for orthopedic and periodontal purposes. A silica-based bioactive glass, known as 1393 bioactive glass [Composition wt.%: 53 SiO₂ – 6 Na₂O – 12 K₂O – 20 CaO – 5 MgO – 4 P₂O₅], is derived from the 45S5 bioactive glass composition but features a higher SiO₂ content and additional network modifiers, such as K₂O and MgO, compared to 45S5. This glass is also used clinically.
In this study, the destructive (DT) and non-destructive (NDT) behavior of 1393 bioactive glass with partial replacement of SiO₂ by boron trioxide (B₂O₃) was investigated. The amorphous phase formed in the bioactive glass was confirmed using X-ray diffraction (XRD) analysis. Density and destructive properties, including microhardness, compressive strength, and flexural strength, were evaluated. Non-destructive properties were assessed using ultrasonic wave velocity measurements to study elastic characteristics. The Young’s modulus, shear modulus, bulk modulus, and Poisson’s ratio of the bioactive glasses were reported.
The results indicate that substituting boron trioxide in 1393 bioactive glass enhances its density, mechanical properties, and elastic characteristics, similar to the effects observed with silica.
