Question

Solid state reactions of inorganic materials generally require long periods of heating at high temperatures. Explain the reasons for this and the steps that may be taken to speed up reactions.

Answer 1

Yes, solid state reacitons (or synthesis) of inorganic materials require high temperature for a long period as we need diffusion of the materials into each other.

So for diffusion we need to increase the temperature.

also the high temperature sometimes also result into formation of stable products.

We may also need high temperature in order to overcome the lattice interactions between ion in the given inorganic materials.However the solids are not heated to melt them.
