What are the advantages and disadvantages of preparing nanoparticles by high temperature solid state method?

The solid phase method is to make powder from the change of solid phase.

The advantages of preparing nanoparticles by high-temperature solid-state method are: convenient operation, simple synthesis process, uniform particle size and controllable strength.

Less pollution, meanwhile, hard agglomeration in liquid phase can be avoided or reduced, and the cost is low.

Disadvantages are: uneven composition, easy agglomeration of particles and wide particle size distribution.
