| titleOfInvention | Preparation method of spherical bioactive glass |
| abstract | The preparation method of the spherical bioactive glass comprises the following steps of carrying out high-temperature self-propagating pretreatment on precursor gel and then calcining the precursor gel, wherein the precursor gel is prepared from tetraethoxysilane, triethyl phosphate, calcium nitrate, magnesium nitrate, glucose, ethanol and deionized water, and the weight ratio of the tetraethoxysilane to the triethyl phosphate to the calcium nitrate to the magnesium nitrate to the glucose is 550-650: 200-300: 850-950: 100-200: 1000 to 2000 parts; in the preparation process, nitric acid solution is added to make the pH value of the precursor sol be 2. The invention adopts glucose as a template agent, is easy to remove at high temperature, is not easy to remain and has low cost; the pretreatment is carried out by a high-temperature self-combustion method, the process is simple, the energy consumption is low, and the large-scale production is facilitated. |
