Multifunctional composites by high-pressure spray processesWeidner, Eckhard (Avtor) Petermann, Marcus (Avtor) Knez, Željko (Avtor) chemical processinghigh pressure technologymicronizationsupercritical fluidsparticlespowder generationthermodynamicsfluid dynamicsPGSSA series of spraying processes designed to generate powders and composites using supercritical fluids have been proposed in the past 15 years. In this review, thermo- and fluid-dynamic aspects and engineering principles are discussed and advantages of such technologies are demonstrated. These new techniques display convincing advantages, producing competitive high-quality products with tailor-made properties. Initial industrial applications have been achieved in the production of food products and fine-chemicals.20032012-06-01 12:50:14Neznano27754sl
