Various grades of calcined kaolin are produced by varying parameters in the calcination process (e.g. retention time in the rotary kiln, firing temperature). Calcination initially converts it to metakaolin (whose reactivity makes it useful in cements).
Chemical analysis of the kaolin ash (Table 1) indicates that it contains 44.70 wt.% of SiO2 and 23.90 wt. of Al2 O3 with SiO2 /Al2 O3 ratio equal to 1.87, which is similar to the ratio in the original kaolin sample. Na2 O increased from 0.02% in the original kaolin to 16.40% in the kaolin ash due to calcination with NaCl (see Figure 2). 5.2.

Alkali calcination method is a kind of hydrothermal synthesis method, but their calcination processes are different. Alkali roasting method is to mix alkali with kaolin and then roasting at 600–700 °C. The calcination products obtained by alkaline calcination method have no quartz peak, high crystallinity and few other hetero crystalline peaks.

The calcination of kaolin in industry is commonly carried out using rotary kilns and multiple hearth furnaces (MHF) (Jämsä-Jounela et al., 2018).While this process does not produce harmful gases that pollute the environment, it requires a significant amount of energy, often derived from the combustion of fossil fuels such as oil or coal (Tasiopoulou et al., 2023).
This study offers a new conceptual approach to the use of SWIR spectroscopy for the characterization the calcination of kaolin, withdrawing the need of using extensive laboratory techniques.
