Published: 29 November 2023
Clay Minerals (2023) 58 (4): 353–363.
... the possibility of using kaolin clays from Cameroon in the production of dense refractory bricks. The reason for such a study is to optimize the economic potential of a locally available resource for the production of added-value materials. To such an end, it is necessary to choose deposits with sufficient...
