摘　　要：熔融物用热水浸取后,经过滤分离去除了干扰元素钒,从而改进了测定高钛冷固球中二氧化钛的标准方法,实验并确定了测定过程中的最佳分析条件。应用该法分析高钛冷固球中的二氧化钛含量,其相对标准偏差<0.4%,结果与标准方法相比误差更小。The melt was leached with hot water, the interference element of V was removed after filtration and separation, the standard method for determining of titanium dioxide content in cold-bounded high-titanium ball was improved, and the optimal analytical conditions were tested and obtained. This method was applied to determine titamium dioxide in cold-bounded high-titanium Ball, and the relative standard deviation （RSD） was smaller than 0.4%. Compared with the standard method, this method error was less.
