摘要
本文以分析纯硝酸钙和硅酸钠为原料 ,采用直接沉淀法制备了硅灰石超细粉体。讨论了反应物浓度和热处理制度对产物粒径的影响。
In this work,,ultrafine wollastonite powder was prepared by direct precipitation method using Ca(NO 3) 2·4H 2O and Na 2SiO 3·9H 2O(AR) as starting materials.The effects of reagent's concentration and heat-treatment process on particle size were discussed;The bioactivity ultrafine wollastonite powder was studied by soaking the CaSiO 3 powders before and after in simulated body fluid solution for various times and different conditions.
