传统沉淀法制白炭黑的研究进展

The research progress of preparation of white carbon by traditional chemical precipitation method

综述了传统沉淀法制备二氧化硅粒子(白炭黑)的过程,以及影响白炭黑颗粒大小的因素,包括表面活性剂和分散剂、沉淀剂及沉淀方式等的影响。指出此种方法制备的白炭黑并不具有科学意义上的纳米实质,同时指出传统沉淀法制备白炭黑的研究重点应侧重于改进其分散性能。

The process of preparing SiO2 particle （ white carbon） by traditional precipitation method and its effecting factors,such as surfactant and dispersant,precipitator and precipitating form on the particle size are reviewed. It is pointed out that this kind of SiO2 manufactured by traditional precipitation method is not the nano - material in essence of science, and the key point of study for this product should be to improve the dispersing performance.
