摘　　要：研究了煅烧温度对锐钛型钛白消色力、白度、形貌及粒径的影响规律,并通过拉曼光谱、颜料性能检测、SEM对煅烧样品进行表征。结果表明：随着煅烧温度从915℃增加至970℃,消色力逐渐增加,蓝相逐渐降低;较高煅烧温度下钛白粒子将发生烧结,平均粒径增大至310 nm,且不均匀。935~945℃为最佳煅烧温度,得到的钛白粒径为260 nm,粒度分布较窄,消色力大于1 500,蓝相大于4.0。The effect of calcination temperature on the achromic ability, whiteness, morphology and particle size of anatase titanium dioxide were studied in this paper, and the calcinated samples were charac- terized by Raman spectra, pigments properties test and SEM. The results show that with calcination tem- perature increasing from 915℃ to 970℃, the achromic ability of the sample gradually increases while its blue phase gradually decreases. The particles of titanium dioxide sinters under higher temperatures and the average particle size increases to 310 nm, with heterogeneous particle size distribution. The optimum calcination temperature is determined to be 935 - 945℃, under which the titanium dioxide owning narrow size distribution can be obtained with 260 nm of particle size, more than 1 500 of achromic ability and more than 4.0 of blue phase.
