Abstract
The invention relates to a method for producing bioactive borate glasses, comprising the following steps:a) mixing of precursors of B2O3, CaO, Na2O and P2O5 in a solvent for 12-48 hours, in a temperature from 20 to 40°C, to obtain a sol;b) freezing the sol obtained in step a) in a temperature from -10 to -196 °C, and then freeze-drying to obtain an aerogel;c) grinding the aerogel obtained in step b) and sieving through a sieve with a mesh size of 40-100 µm;d) heating the aerogel sieved in step c) according to the following temperature treatment scheme:- heating the aerogel at a speed ranging from 1,5 to 3 °C/min up to a temperature ranging from 100 to 150 °C;- maintaining the aerogel in a temperature ranging from 100 to 150 °C, over time from 24 to 72 hours;- heating the aerogel at a speed ranging from 1,5 to 3 °C/min, up to a temperature ranging from 400 to about 600 °C;- maintaining the aerogel in a temperature ranging from 400 to about 600 °C, over time from 1,5 to 6 hours;- free cooling of the furnace.
