钛酸钾导电晶须的制备与研究

Study of Preparation and Properties of Conductive Potassium Titanate Whisker

通过固相反应法,在K2O与TiO2的摩尔比为1:2,温度810℃下保温2 h得到生长良好的钛酸钾晶须。利用化学镀的方法,在锌离子和肼的双重催化下,在制备好的钛酸钾晶须上镀上一层金属镍。测试得导电晶须的最小体积电阻率为52.41Ω·m。

Through the solid phase reaction method,the molar ratio of K2O to TiO2is 1:2,the temperature 810 ℃ for 2h to get good growth of potassium titanate whiskers. Through chemical plating method,the preparation of potassium titanate whiskers are coated with a layer of metal nickel in both the catalytic zinc ion and hydrazine. The result show the minimum volume resistivity is 52. 41 Ω·M.
