Parameterization of SiO2 Nanoparticles Preparation Route and Evaluation of the Reaction Parameters Using Fuzzy Mathematics
In this work,SiO2 nanoparticles were prepared via hydrolysis method,chemical precipitation method and sol-gel method,respectively.And the effects of various experimental conditions on the unit output,yield,particle size and size distribution of SiO2 nanoparticles were studied and parameterized.Meanwhile,a set of evaluation systems were constructed with fuzzy mathematical analysis and modeling which the complex data can be evaluated systematically with concise and precise unity.The results indicate that Si and Na2SiO3 are suitable raw materials for the industrial production of 20 nm and 60 nm SiO2 nanoparticles and the maximum weighted average can reach the high level of 81.3 and 82.95,respectively.Also,SiO2 nanoparticles with 250 nm ought to be prepared using TEOS as the raw material,and its maximum weighted average is 85.Moreover,the results also show that the order of the effects of the factors in hydrolysis is the dosage of sodium silicate > the amount of silica powder > the reaction time.For the chemical precipitation method,the order is the pH value > the reaction time > the reaction concentration.For the sol-gel method,the order is the amount of ammonia water > TEOS consumption > the reaction time.
