Preparation and Application of Calcining Seed in the Production Process of Rutile Titanium Pigment
金红石型钛白粉生产过程中煅烧晶种的制备与应用

Calcining seed of rutile titanium dioxide was prepared at low temperature using metatitanic acid as raw material through alkaline hydrolysis,hydrolysis reaction,first washing,neutralization reaction,second washing and acid dissolution.These kinds of seed were added in the salt treatment,and the influences of calcining seed and calcination temperatures on the content of rutile TiO2 pigment were examined systemically.The results indicated that above 90% rutile titania gel with high stability could be obtained...
