Abstract: The invention relates to a process for the production of pure lithium oxide and its use, wherein lithium carbonate is reacted with finely divided, elemental carbon in powder form in the temperature range between 600 and 1200° C., wherein the two reactants are intensively premixed prior to the thermolysis process so that the bulk density of the mixture is reduced by at least 5%, preferably by at least 15%.

Abstract: A method for manufacturing alloy powders based on titanium, zirconium and hafnium alloyed with the elements Ni, Cu, Ta, W, Re, Os, and Ir is described in which an oxide of Ti and Zr and Hf is mixed with a metal powder of the elements named and with a reducing agent, and wherein this mixture is heated in a furnace, optionally under a argonate atmosphere or, optionally under hydrogen atmosphere until the reducing reaction begins, the reaction product is leached and then washed and dried, wherein the oxide used has an average grain size of 0.5 to 20 ?m, a specific surface area according to BET of 0.5 20 m2/g and a minimum content of 94 wet. ?%. An easy to produce powder, in particular in relation to the ignition point and burning time, is produced.
