Abstract
The project aims to apply the knowledge about the clay pillaring process to sinthesize Hydroxy interlayered 2:1 (HI2:1), usually found in small amount in tropical soils. These minerals show variable intercalation degree (ID), and the reasons for that are not yet well known. Phyllosilicates 2:1 HI will be sinthesized in controled conditions using standards from the Clay and Clay Minerals S…
