Advances in Application of Natural Clay and Its

Qualitative mineralogical characterization of the clay revealed that the clay contains illite, distorted kaolin-ite, mixed layer minerals, and nonclay mineral carbonate fluoroapatite. pH pzc for the raw clay, as determined by potentiometric titrations, was 9.66, while pH pzc of pre-treated clay was 9.63. Pretreatment of the clay involved removal of carbonates, iron oxides, and organic matter

Fillers for papermaking A review of their properties

Though many other minerals, such as kaolin clay, cannot match the pitch-absorbing characteristics of talc, their performance in such applications can sometimes be improved by pretreatment. For example, Carter and Hyder (1993) showed that kaolin treated with a highly cationic polymer was more effective for pitch removal, especially when combined with retention aid use. The polymer-treated clay

Nanostructured Wood Hybrids for Fire-Retardancy

Eco-friendly materials need "green" fire-retardancy treatments, which offer opportunity for new wood nanotechnologies. Balsa wood (Ochroma pyramidale) was delignified to form a hierarchically structured and nanoporous scaffold mainly composed of cellulose nanofibrils. This nanocellulosic wood scaffold was impregnated with colloidal montmorillonite clay to form a nanostructured wood hybrid

The present study was carried out on the effect of acid leaching on the modification and structure alteration of montmorillonite. A nanostructured, activated material was prepared by selective leaching of pure smectite clay with different concentrations of sulfuric acid (1 10 N/L) at 85°C for 120 min using a solid/liquid ratio of 120 and a reflux system.
