Determining the Thermal Behaviour of Bioactive Glasses by using Differential Scanning Calorimetry.
Pak J Med Health Sci Jan ;12(4):1389-91.

Background: The structural transformations of the bioactive glass ICI16M has been discussed during thermal treatments. The most common use of Differential scanning calorimetry is to find out the glass transition (Tg) range and the temperature of crystallization for both ceramic and glass. Method: Stanton Redcroft, DSC 1500 R heomatric Scientific, Epson, UK ) was used to measure glass transition temperature and crystallisation behaviour of the glasses using thermal analysis soft ware (TAS- infinity pro soft ware) . Results: The glass transition temperatures for ICIE16M can be seen at 560˚, 670˚ and peak of crystallization could be seen at 860˚. The two glass transition temperatures present indicate that the glass has a two phase system which means a silicate phase and other is a phosphorus phase. Conclusion: The DSC traces further show that the crystallization phases only used a small amount of the total volume of glass powder and the less than 38 micron particle size glass powder showed reduced crystallization phases and more bioactive nature. Further future work is required in order to get glasses with more bioactive properties and compressive strength in order to diversify its usage in bone replacement scaffolds and dental implants.
