Abstract: A method of forming at least partially crystalline ceramic powder includes providing mixed metal oxide particles in an aqueous suspension in a hydrothermal treatment vessel, heating the aqueous suspension at a temperature of at least 150° C. at a treatment pressure of at least 200 psi, and adding an aqueous solution having a temperature of not greater than 100° C. to the hydrothermal treatment vessel while heating and while releasing steam from the hydrothermal treatment vessel.

Abstract: An electronically controlled journal loading system 20 for controlling and adjusting the amplitude of the load applied to a journal assembly 19 of a pulverizing mill 10. The journal loading system 20 includes a servomotor 44, resolver 134, vertical gearbox 42, coil spring assembly 40, controller 46 and a user interface 48. The journal loading system 20 provides electronic control and adjustment of the force applied to the journal assembly 19 to thereby increase or decrease the load that a grinding roll 18 imposes on the material being pulverized. In the mode of operation of the servo journal loading system 20, a desired load set point is selected via the user/operator interface 48. The servomotor 44 rotates a preload stud (or servo screw) 50 within the coiled spring assembly 40 in the appropriate direction via the gearbox 42. As the preload stud 50 turns, a bronze nut 100 and bushing 94 move axially along the stud to compress or decompress the spring 86.

Abstract: An electrical-energy-storage unit (EESU) has as a basis material a high-permittivity composition-modified barium titanate ceramic powder. This powder is double coated with the first coating being aluminum oxide and the second coating calcium magnesium aluminosilicate glass. The components of the EESU are manufactured with the use of classical ceramic fabrication techniques which include screen printing alternating multilayers of nickel electrodes and high-permittivitiy composition-modified barium titanate powder, sintering to a closed-pore porous body, followed by hot-isostatic pressing to a void-free body.

Abstract: An electrical-energy-storage unit (EESU) has as a basis material a high-permittivity composition-modified barium titanate ceramic powder. This powder is single coated with aluminum oxide and then immersed in a matrix of poly(ethylene terephthalate) (PET) plastic for use in screen-printing systems. The ink that is used to process the powders via screen-printing is based on a nitrocellulose resin that provide a binder burnout, sintering, and hot isostatic pressing temperatures that are allowed by the PET plastic. These lower temperatures that are in the range of 40° C. to 150° C. also allows aluminum powder to be used for the electrode material. The components of the EESU are manufactured with the use of conventional ceramic and plastic fabrication techniques which include screen printing alternating multilayers of aluminum electrodes and high-permittivity composition-modified barium titanate powder, sintering to a closed-pore porous body, followed by hot-isostatic pressing to a void-free body.

The components are configured into a multilayer array with the use of a solder-bump technique as the enabling technology so as to provide a parallel configuration of components that has the capability to store electrical energy in the range of 52 kW·h. The total weight of an EESU with this range of electrical energy storage is about 336 pounds.
