Abstract: A process for production of a borohydride compound M(BH4)y. The process has three steps. The first step combines a compound of formula (R1O)yM with aluminum, hydrogen and a metallic catalyst containing at least one metal selected from the group consisting of titanium, zirconium, hafnium, niobium, vanadium, tantalum and iron to produce a compound of formula M(AlH3OR1)y, wherein R1 is phenyl or phenyl substituted by at least one alkyl or alkoxy group; M is an alkali metal, Be or Mg; and y is one or two; wherein the catalyst is present at a level of at least 200 ppm based on weight of aluminum. The second step combines the compound of formula M(AlH3OR1)y with a borate, boroxine or borazine compound to produce M(BH4)y and a byproduct mixture containing alkali metal and aluminum aryloxides. The third step separates M(BH4)y from the byproduct mixture.

Abstract: The method forms forming an open-network polishing pad useful for polishing magnetic, semiconductor and optical substrates. The method provides a polymer sheet or film of a curable polymer and exposes the polymer sheet or film to an energy source to create an exposure pattern in the polymer sheet or film. The exposure pattern having elongated sections exposed to the energy source. After attaching the polymer sheet or film to an open-network substrate, the method removes polymer adjacent from the exposed polymer sheet or film of the intermediate structure with a solvent. This forms elongated channels through the polymer sheet or film in a texture pattern that corresponds to the exposure pattern with the open-network supporting the polymer. The elongated channels extending through the thickness of the polymer sheet or film to form the open-network polishing pad.
