Abstract	Current research is intended to study the structure phenomenon of natural nano silicate layers. The research studies the effect of water on the structure of the material and also, the stresses due to the effect of drying of the material. The research includes a study of the change of structure, fracture, cracking mechanism, crack propagation, crack branching and bifurcations. The results conclude that the silicate layers are very sensitive to temperature. Cracks and fracture will be produced due to the loss of water due to shrinkage as the effect of heat loss or temperature changes. One of the most important properties of the nano silicate is the hydrophilic property. This property makes it very sensitive for absorbing water or losing it. As a result of absorbing water the silicate volume changes by swelling while due to loss of water or drying the silicate will shrink. If the silicate is dried, it will be fractured. It is found that if the nano silicate is added to another matrix material representing filler or reinforcement for that main material temperature stability and temperature resistant material. If it is mixed with polymers under certain conditions it can produce high quality material of nanocomposite. A mechanism of silicate cracking is proposed. A new and special version of directional fracture theory called (RM-K) theory is proposed for the application of silicate cracking since it follows different behavior than the normal fracture approach.
