Classification of Silicate Clays | Soil Science

On the basis of number and arrangement of tetrahedral and octahedral sheets, silicate clays are classified into 3-different groups: 1. 1:1 Type Clay Minerals 2. 2:1 Type Minerals 3. 2: 1:1 Type Minerals. 1. 1:1 Type Clay Minerals: Such silicate clay is made up of one silica sheet and one alumina sheet combined. In soils, Kaolinite is the prominent member [...]

Silicate Clays: Concept, Structure and Sources | Soil Colloids

After reading this article you will learn about:- 1. Concept of Silicate Clays 2. Structure of Silicate Clays 3. Classification 4. Sources of Negative Charges. Concept of Silicate Clays: (i) Size and Chemical Composition: The chemical analysis of clay indicates the presence of silica, alumina, iron and combined water. These make up from 90-98 per cent of the colloidal clay. [...]
