Abstract: A capacitor comprising an aluminum anode and a dielectric layer comprising phosphate doped aluminum oxide and process for making the capacitor. The capacitor has a CV Product of at least 9 ?F?V/cm2 at 250 volts. Furthermore, the capacitor is formed by the process of: forming an aluminum plate; contacting the plate with an anodizing solution comprising glycerine, 0.1 to 1.0%, by weight, water and 0.01 to 0.5%, by weight, orthophosphate; applying a voltage to the aluminum plate and determining an initial current; maintaining the first voltage until a first measured current is no more than 50% of the initial current; increasing the voltage and redetermining the initial current; maintaining the increased voltage until a second measured current is no more than 50% of the redetermined initial current, and continuing the increasing of the voltage and maintaining the increased voltage until a final voltage is achieved.

Abstract: The metal oxide surface coating of an anodized valve metal may be made conductive under certain conditions so that conductive coatings can be electrolytically deposited on the surface of the oxide. When a dry polar aprotic electrolyte solution is used at a reduced temperature and a relatively high field is applied, the oxide ceases to be insulative. The process is reversible, meaning that there is no permanent change in the oxide.

Abstract: An apparatus is disclosed for drying materials wet with one or more solvents, particularly hygroscopic materials and materials wet with a high boiling point (low vapor pressure) solvent that are sensitive to heat. Wet material is loaded into a chamber, which is then sealed and caused to oscillate back and forth. Vacuum is enlisted to provide rapid evaporation of solvent at a lower temperature than possible at standard atmospheric pressure. The material is oscillated until a sudden decrease in the residual pressure of the chamber, which indicates completion of the drying cycle. Because vacuum is applied to an oscillating chamber, a rotary vacuum seal is not required to accomplish drying in accordance with the practice of the instant invention.
