Mineralogical Composition of Structural Clay Products
When clay materials are tempered with water to produce the plasticity necessary for proper workability, it is the clay minerals that are responsible for these properties. To understand the interaction between clay minerals and water, it is necessary to know the crystal structures of the various clay minerals. In addition, many of the disilicate minerals other than those of clays are often found in, or added to, the raw materials for structural clay products. These other disilicate minerals are of more concern in the firing operation than in the development of plasticity, but the crystal structures of these minerals, as well as the clays, is important in following the progress of the high-temperature reactions. The structural clay products engineer and scientist cannot solve the technical problems that arise without a good foundation in the crystal structures of the disilicate minerals.
