This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The crystal structure, particle size distribution and impurity content of metatitanic acid had great impacts on the structures and pigment properties of rutile titanium dioxide pigment, and appropriate structure of metatitanic acid was helpful to prepare titanium dioxide with excellent pigment properties. The rutile titanium dioxide white pigment was produced via short Sulfate Process from unenriched low concentration industrial TiOSO4 solution. In order to produce rutile TiO2 pigment with good structures and excellent pigment properties, the crystal size of metatitanic acid should be controlled less than 8.9 nm and as close as possible to 7.9 nm, which could effectively promote the phase transformation and crystal growth of the rutile TiO2. The appropriate particle size distribution of metatitanic acid had obvious effects on obtaining rutile TiO2 with narrower particle size distribution and near 0.20 u00b5m. It was best to adjust the hydrolysis conditions to reduce the specific surface area of metatitanic acid so as to reduce the iron ion impurity adsorption.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rutile titanium dioxide pigments were prepared by using metatitanic acid as raw material hydrolyzed from industrial low concentration titanyl sulfate solution via short sulfate process. The orthogonal interactions of the addition of salt treatment agent (ZnO, K2O, P2O5) and the highest calcination temperature were investigated by using four-factor quadric orthogonal regression test. The metatitanic acid and rutile TiO2 were characterized by XRD, particle size distribution and pigment properties test. The different salt addition and the highest calcination temperature had great effects on the achromatic power (TCS) of the rutile TiO2 pigments. The orthogonal interactions regression model to TCS was built and showed highly repeatability and stability, which could be used to forecast the pigment properties and preset the salt treatment and calcination conditions. And the optimal salt treatment conditions were ZnO of 0.36%, K2O of 0.70%, P2O5 of 0.20%, and the highest calcination temperature of 850 0C.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The composition and structure of industrial metatitanic acid played a decisive role on the crystal structure of titanium dioxide, affecting the purity of titanium dioxide. High purity titanium dioxide was prepared from low concentration industrial titanyl sulfate by Sulfate Process. The effects of preadding water volume ratio, aging time, total TiO2 concentration on the particle size distribution, crystal size and titanium dioxide content of metatitanic acid were investigated. The preaddind water volume ratio determined the concentration, quantity and activity of the hydrolysis seeds, affected the integrity of metatitanic acid particles and cell parameters, which had important impacts on the purity of titanium dioxide. The aging time and total titanium concentration affected the particle size distribution of metatitanic acid, the purity of titanium dioxide. The optimum conditions were that the preadding water content was of 60%, the aging time was of 20 min, and the total TiO2 concentration was of 180.4 g/L, the particle size distribution was narrowest and the grain size was relatively smaller, and the purity of titanium dioxide was the highest, with TiO2 content of 99.98%.

Book excerpt: This book deals with the synthesis, properties and applications of titanium dioxide (TiO2) which is a naturally occurring oxide of the element titanium. In nature these oxides are found in well-known minerals such as Rutile, Anatase and Brookite. However, it is most commonly extracted from titanium tetrachloride by carbon reduction and re-oxidisation. Alternatively, it may be processed from another oxide called ilmenite, which is subjected to reduction with sulphuric acid to achieve pure titanium dioxide.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Using low concentration industrial titanyl sulfate solution as raw material, rutile titanium white pigment was prepared via the self-seeded thermal hydrolysis sulfate process. The effects of pre-adding water, feeding rate and aging time on the particle morphologies, particle size distribution and pigment properties of rutile titanium dioxide white pigment were investigated. The as-prepared samples were characterized by particle size distribution test, SEM, XPS, TEM and pigment properties test. The results showed that the optimal hydrolysis operating conditions was the pre-adding water ratio of 22% of, the feeding rate of 8.3 r/min, and the aging time was of 30min. The obtained rutile titanium white pigment was with suitable particle size, narrow particle size distribution and good pigment properties. The effects order on the pigment performances from large to small was the pre-adding water volume ratio, the feeding rate and the aging time.

Book excerpt: The particle size and its distribution of metatitanic acid determines the particle size distribution and pigment properties of titanium dioxide pigment, it is great important to characterize the particle size distribution of metatitanic acid particles. Using metatitanic acid slurry hydrolyzed from industrial low concentration titanyl sulfate solution via short sulfate process as research object, the effects of dispersing media, dispersant and dispersing conditions on the particle size distribution by photon correlation spetroscopy were investigated. Proper dispersion media, dispersant and its concentration, ultrasonic vibration would all improve the Zeta potential of metatitanic acid particles, enhance the repulsion between particles and strengthen particle dispersion. The optimal dispersion conditions for metatitanic acid were slurry dosage of 0.044 g, 50 ml of 0.05% aqueous sodium hexametaphosphate solution, mechanical stirring time of 2 min, ultrasonic vibration time of 5 min. After thorough dispersion, the particle size distribution of metatitanic acid must be determined immediately.

Book excerpt: Hydrolysis of unenriched low concentration industrial titanyl sulfate solution affected SO42-, and obtained metatitanic acid sample predominantly amorphous component, containing a small amount of anatase crystal structure of particles, which TiO6 octahedral distortion occurs, a-axis reduce, c-axis increases. These samples have a porous structure, having a surface area in the vicinity of 286 m2/g, smaller pore size, larger pore volume, moisture volatiliza and SO42- decompose in metatitanic acid, drastically reduce the specific surface area, grain coalescence than grow , particle gap increases, the pore volume reduce after calcination. With prolonging hydrolysis time, the grain size is increase, and the grain growth can be divided into three stages: rapid growth phase, the transition phase and the grain growth of slow growth. Grain growth and particle aggregation have important relationship, mainly is aggregated between particles in the early, the latter mainly is ion attachment grew up in the particle surface.
