Plasma spraying of natural kaolinite and metakaolinite
Boletín de la Sociedad Española de Cerámica y Vidrio, 2021 Metakaolinite was obtained by thermal treatment of natural kaolinite. Both of them, kaolinite with structurally bonded water and metakaolinite without it, were, after sieving to acceptable size fraction, plasma sprayed.

Microwave-Assisted Synthesis of Zeolite A from Metakaolinite for CO2 Adsorption. [PDF]
Int J Mol Sci, 2023 The global demand for energy and industrial growth has generated an exponential use of fossil fuels in recent years. It is well known that carbon dioxide (CO2) is mainly produced, but not only from fuels, which has a negative impact on the environment, such as the increasing emission of greenhouse gases. Thus, thinking about reducing this problem, this
