Clay calcination technology: state-of-the-art review by the …

Industrial kaolins, which encompass pure kaolin, refractory clays, and bauxitic kaolin, among others, are distinguished by their relatively high content of clay minerals from the kaolinite group. Bentonite clay deposits, containing a high amount of clays from the smectite group (e.g. montmorillonite), are prized for their high cation exchange ...

Is Is Possible To Calcine Your Own Kaolin?

When you calcine kaolin, you burn off the chemical water as well as any other organics- the stuff that's listed as L.O.I (Loss On Ignition) when you look at the makeup of a clay. So basically you're pre-shrinking the clay. In the case of kaolin, you're getting rid of about 15% shrinkage, which is significant if you've got a glaze or such that's ...

Characterization and thermal behavior of kaolin

The decomposition behavior of kaolin samples has been carried out by simultaneous TG–DTA experiments. New layer-structure formation during the calcination process was found, and metakaolin compound was detected between 600 and 900 °C. The thermal stability of kaolin samples was then identified by TG–DTA, and the results are …
