Abstract: Static charges and agglomeration of particles in a fluidized bed system are minimized by maintaining in at least part of the bed a radio frequency glow discharge. This approach is eminently suitable for processes in which the conventional charge removing agents, i.e., moisture or conductive particle coatings, cannot be used. The technique is applied here to the disproportionation of calcium peroxide diperoxyhydrate to yield calcium superoxide, an exceptionally water and heat sensitive reaction.

Abstract: A plasma polymerization process for the deposition of a dielectric polymer coating on a substrate comprising disposing the substrate in a closed reactor between two temperature-controlled electrodes connected to a power supply, maintaining a vacuum within the closed reactor, causing a monomer gas or a gas mixture of a monomer and diluent to flow into the reactor, generating a plasma between the electrodes, and varying and controlling the dielectric constant of the polymer coating being deposited by regulating the gas total and partial pressures, the electric field strength and frequency, and the current density. A monomer, such as a polar saturated or unsaturated nitrogen-containing compound, or a monomer and diluent, such as a saturated or unsaturated aliphatic hydrocarbon and nitrogen, can be polymerized to form a dielectric coating having a varying dielectric constant in accordance with this plasma polymerization process.
