Diatomite Processing. A 25% addition of a fluxing agent during calcination at up to 1,200°C reacts with ironcontaining impurities to yield a white product for paint filler applications. Flux calcination also improves filtration properties and the release of cations from diatomite during filtration. At the same time cristobalite is formed.

Table I shows the chemical analysis of diatomite (D), calcined diatomite (CD) and titania (T). It can be seen that the calcined diatomite is composed basically of SiO 2 and Al 2 O 3, with small quantities of others oxides, while titania has purity larger than %.
