This formation of a gel from the sol gives the materials the name sol–gel (Fig. 3). This cross-linking is achieved through a polycondensation step. This step is the same as the condensation step, except that it results in a structure that is highly cross-linked.

Web[16] [17] The gel is initially formed by the assembly of particles into a space-spanning network, leading to a phase arrest. In the aging phase, the particles slowly rearrange to form thicker strands, increasing the elasticity of the material. Gels can also be collapsed and separated by external fields such as gravity.
