This chapter discusses solid-state reactions, which are essential in materials science. Sintering is a solid-state reaction that occurs without change of composition, the driving force being the lowering of the interfacial and surface free enthalpies. In the absence of a liquid phase, material ...

In the solid-state, the surrounding is virtually stationary as the atomic distances are in angstroms range. As a result, there is a possibility of reactants to assume geometries in the solid-state, which may be unfeasible to achieve in the solution-phase. In such solid-state reactions, lowe...
The elementary processes contributing to solid state reactions are subdivided in homogeneous processes and in heterogeneous processes such as exchange processes at interfaces, pore formations and precipitations. It is shown that there are different types of miscibility gaps that can be of influence on ...
