| 摘 要： | A new stearic acid method(SAM) has been used to prepare ultrafine K2La2Ti3O10 nanocrystalline. Each state of synthesis process was followed by the use of FT-IR analysis. The resulting materials have been characterized by means of XRD， TEM， BET surface area analysis. The acid-exchanging property of the obtained product was also studied. The experimental results showed that comparing with the product of traditional solid-state reaction， the particle size of the K2La2Ti3O10 synthesized by SAM is greatly reduced， BET surface area is high(more than 11.83m2·g-1) and has different acid-exchanging properties. It can be easily exfoliated in 2mol·L-1 HNO3 so-lution.
