Effect of hydrolysis on High-purity TiO2 Size for PTC Thermistor

摘要：

　　The effect of self-generated seeded thermal hydrolysis factors,such as TiOSO4 solution concentration,grey aging time,volume ratio of TiOSO4 to pre-adding water,and heating rate on high-purity TiO2 size for PTC thermistor were studied.The samples were characterized by particle size distribution,and SEM.The results show that with increase of TiOSO4 solution concentration,the high-purity TiO2 size decrease gradually,but with increase of grey aging time and volume ratio of TiOSO4 to pre-adding water respectively,the high-purity TiO2 size also increase.The suitable TiOSO4 concentration is 160g/l,grey aging time is 15min,the optimum volume ratio of TiOSO4 to pre-adding water is 4.0∶1 and heating rate should be 1.5℃/min.
