Pure titania pulp containing amorphous titania was heated at different temperatures and times. Above 650°C anatase phase was evolved and between 900 and 1000°C, anatase–rutile transformation occurred. The anatase–rutile transformation in TiO2 i

Titanium dioxide shows polymorphism on heating at high temperature. This strongly depends on temperature and duration of heating. When amorphous titania pulp was heated at different temperatures and time between 900 and 1000 °C, anatase–rutile tra

Metal oxides supported on TiO2 are gaining in importance as a result of their applications in catalysis. Reactions carried out over TiO2 supported catalysts include hydrodesulphurisation (HDS), partial or selective oxidation, hydrogenation of carbon

TiO2 is produced and marketed in two main grades viz. anatase and rutile. Both anatase and rutile have their own pigmentry properties and hence cannot be substituted by each other. Pure anatase on heating at higher temperatures undergoes crystallogra

Investigations carried out to accelerate the rusting of reduced ilmenite show that the addition of small quantities of carbonyl compounds such as glyoxal, glucose and sucrose with NH 4 Cl considerably increases the efficiency of the reaction and the

Magnetic fractionation, chemical, and structural analyses prove that alteration of ilmenite from Manavalakurichi deposit extends only up to the formation of pseudorutile with traces of rutile. The data indicate that ferrous to ferric iron transformat
