Title: Method of making alkali metal hydrides

Abstract

A method is provided for making alkali metal hydrides by mechanochemically reacting alkali metal and hydrogen gas under mild temperature (e.g room temperature) and hydrogen pressure conditions without the need for catalyst, solvent, and intentional heating or cooling.

  • This patent describes a method for producing a lead-acid battery having a thixotropic gel electrolyte. The method comprising combining an aqueous colloidal dispersion of alkali metal polysilica with sulfuric acid while introducing the combination into a lead-acid battery precursor.
  • This patent describes a lead-acid battery. It comprises: a battery case; positive and negative metal plates spaced one from another within the case; and a thixotropic gel electrolyte within the case and providing electrolytic connection between the positive and negative plates, comprising alkali metal polysilica; sulfuric acid; and water.
  • A method is described for preparing alkali metal boranes from boron halide or its addition compounds with the help of alkali metal hydride or alkali metal and hydrogen, especially in the presence of a tertiary amine. It is proposed to use alkyl boric acid diamides or dialkyl boric acid amides as boron amide catalyzer. (Gmelin Institute)
  • The invention relates to the preparation of metal shapes from zirconium hydride by powder metallurgical techniques. The zirconium hydride powder which is to be used for this purpose can be prepared by rendering massive pieces of crystal bar zirconium friable by heat treatment in purified hydrogen. This any then be ground into powder and powder can be handled in the air without danger of it igniting. It may then be compacted in the normal manner by being piaced in a die. The compact is sintered under vacuum conditions preferably at a temperature ranging from 1200 to 1300 deg C andmore » for periods of one to three hours.« less
  • A method and apparatus are disclosed for transferring heat to or from metal hydrides contained in storage containers as hydrogen gas is being charged to or withdrawn from the storage containers, wherein the hydrogen gas being charged to or withdrawn from the storage containers functions as a convective energy carrier. A plurality of the containers are connected together in flow communication in series, so that when a pressure differential is established across the series of containers, hydrogen gas associated with the metal hydride will flow from one container to the next container in the direction of the lower pressure. Amore » pressure differential is created across the series of containers by charging hydrogen to either the first or last container in the series, or by withdrawing hydrogen from either the first or last container in a series of containers that has been previously charged with hydrogen. Hydrogen gas flowing through the conduits connecting adjacent containers is heated or cooled in heat exchanger means associated with the conduits. The pressure differential across the series of containers can be periodically reversed by periodically alternating charging hydrogen to the first and last containers of the series during the charging of said containers, and by periodically alternating the discharge of hydrogen from the first and last containers of the series when hydrogen is being withdrawn from the series of containers.« less
