Abstract: A method of producing abrasive tools with abrasive particles consisting of Al2O3 has the steps of producing a mixture of initial components with particles of Al(OH)3, forming blanks of an abrasive tool from the mixture of the initial components with the particles of AL(OH)3, subsequently producing the abrasive tools with the abrasive particles of Al2O3 by subjecting the blanks to a heat treatment such that the particles of Al(OH)3 are converted into the abrasive particles of Al2O3 in the tools, wherein the forming includes rolling a sheet from the mixture of the initial components with the particles of Al(OH)3 before the heat treatment and conversion of the particles of Al(OH)3 the abrasive particles of Al2O3 which particles of Al(OH)3 are softer than the abrasive particles of Al2O3 and therefore do not damage a rolling equipment, and thereafter separating the blanks of the abrasive tools from the sheet for the subjecting to the heat treatment.

Abstract: Fiber structures that include a catalytic material are provided. The fiber structures (e.g., membranes) may be formed of interconnected carbon fibers. The catalytic material may be in the form of nanosize particles supported on the fibers. In one method of the invention, the structures are produced by electrospinning a polymeric material fiber structure that is subsequently converted to a carbon fiber structure in a heat treatment step which also causes the catalytic material particles to nucleate on the carbon fibers and grow to a desired size. The catalytic material may be uniformly distributed across the carbon fiber structure and the amount of catalytic material may be controlled. These factors may enhance catalytic performance and/or enable using less catalytic material for equivalent catalytic performance which can lead to cost savings, amongst other advantages. The fiber structures may be used in a variety of applications including electrodes in batteries and fuel cells.
