Process for the preparation of an additive-containing anionic clay |
| abstract |
Process for the preparation of an additive-containing anionic clay comprising the steps of (a) preparing a physical mixture by mixing a dry divalent metal compound with a dry trivalent metal compound, said physical mixture being solid at room temperature, (b) calcining said physical mixture at a temperature in the range 200-800°C without performing a prior aging or shaping step, thereby forming a product containing at least 5 wt% of a hydratable compound, and (c) hydrating the calcined mixture in aqueous suspension containing an additive to form the additive-containing anionic clay. This process provides a simple and cost-effective way of preparing additivecontaining anionic clays. The process does neither require aging or reaction steps before calcination, nor does it require precipitation of metal salts or the handling of inhomogeneous slurries. |
