Effect of dehydroxylation/amorphization degree of bentonite on the microstructure, thermal stability, and mechanical strength of basalt epoxy composites

Journal of Materials Research and Technology, 2023
Calcination of smectite clays such as bentonite is tricky due to their 2:1 aluminosilicate structure. Low calcination temperature has minimal effect on the dehydroxylation, specific surface area (SSA), and crystalline nature of bentonite clays whereas ...
