First, the B-BG was synthesized according to our previously developed methods (Ai et al., 2020 (link)). Then, ethanol was briefly dissolved in deionized water under constant magnetic stirring followed by the addition of the respective amounts of the individual precursors. Notably, the precursors were added as stated in the order below and each precursor was ensured that it completely dissolved before the next one was added. Tetraethyl orthosilicate (TEO, Aladdin, Shanghai, China), calcium nitrate tetrahydrate (Aladdin, Shanghai, China), triethyl phosphate (TEP, Aladdin, Shanghai, China), and Trinbutyl Borate (TBB, Aladdin, Tianjin, China) were used as precursors for SiO₂, CaO, P₂O₅, and B₂O₃, respectively. Subsequently, nitric acid (Macklin, Shanghai, China) was added to catalyze the hydrolysis reaction and the resulting solution stirred for 24 h at room temperature. Next, this solution was aged and dried for 48 h at a temperature of 80°C. The resulting gel was dried and calcinated for 2 h at a temperature of 800°C and a heating rate of 1°C min−1 and then naturally cooled in the furnace. Table 1 illustrates the different compositions that were used in the preparation of Boron-containing Bioactive glass samples such as 0B, 1B, and 2B. The calcined product was ground in a mortar and pestle to obtain a fine powder which was sieved through a 200 mesh (75 μm).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
