- Abstract
- Bioglass 45S5 was doped with bismuth oxide in concentrations up to 40 wt.%. The amorphous nature of the synthesized glasses was confirmed by X-ray phase analysis. The influence of Bi2O3 on the properties of bioglass was studied. In a series of samples containing from 0 to 40 wt.% bismuth oxide, their characteristics change as follows: the pH values of the model medium during glass leaching decrease from 7.84 to 7.46; radiopacity increases from 1150 HU to values exceeding 11000 HU; chemical degradation drops from 1.299% to 0.424%; bioactivity decreases in the range of 0 – 10 wt.% and is absent in the range of 20–40 wt.% Bi2O3. Glasses containing up to 10 wt.% Bi2O3 can find application in reconstructive surgery. They have radiopaque and bioactive properties. Glasses containing 20–40 wt.% Bi2O3 have high radiopacity, chemical resistance, and a slight effect on the pH of the medium when dissolved. They may be promising as radiomodifiers in the treatment of malignant neoplasms using radiation therapy.
