Abstract

A process for producing particles of a non-friable eutectic mixture of sodium nitrate and potassium nitrate for solar power station use is disclosed. In one embodiment of the invention, the particles are produced by shock chilling a molten stream of mixed nitrate material and crushing the resulting flakes to a size range of between about -5 mesh and about +30 mesh. In a second embodiment, particles of this size are produced by spray granulation of a concentrated solution of mixed nitrate salts onto a fluidized bed to produce dry, free-flowing, solid spheres. In both embodiments, the particles are extremely hard, resistant to moisture pickup and adaptable to being readily shipped by bulk containers.
