| Résumé : |
This article deals with the treatment of barium sulfate extender pigment with iron oxide and its phenomenological adsorption mechanism in the presence of H+ and OH? ions in solution. The pH range taken in the present study is 5–6. By depositing a ferric oxide layer on barium sulfate particles a novel pigment with better optical and functional performance is obtained. This pigment in various coating systems improves physicochemical performance and acts as an active barrier. The treated pigments can be suitably used in different architectural and industrial coatings. The experimental techniques of surface treatment are discussed, along with the instrumental analysis by SEM, EDAX, XRD, etc. |
