摘　　要：根据 Washburn方程 ,采用透过高度法 ,自行设计了简单的实验装置。提出了相对润湿接触角 ( RWCA)的概念 ,测定了 4个超细 Zr O2A simple experimental apparatus, based on the washburn equation, has been designed to evaluate the wettability of powder by measurement of the permeating height The concept of relative wetting contact angle (RWCA) has been put forward, and values of four kinds of ultra fine ZrO 2 powder have been measured

关 键 词：透过高度法 相对润湿接触角 Washburn方程 纳米粉体 超细ZrO2粉体 润湿接触角
