NOVELTY - The method comprises mixing salts, hydroxides, alkoxides or oxides of alkali- or alkaline earth compounds with salts, hydroxides, alkoxides or oxides of semi-metals, nonmetals or metals and then heating at 100 degrees C. The salts, hydroxides, alkoxides or oxides of alkali- or alkaline earth metals are present in a molar ratio of 1:1 or in excess in relation to the salts, hydroxide, alkoxides or oxides of the semi-metals, nonmetals or metals. The salts, hydroxides, alkoxides or oxides of alkali- or alkaline earth compounds are alkali- or alkaline-earth sulfates, chlorides, nitrates, carbonates.    USE - Method for producing alkali- and alkaline earth alloys useful as additive in fluid or solvent, in fuel or in solid body from catalyst, as light metal alloy, as coating material containing noble metal, as oxidation catalyst, reduction catalyst, reaction catalyst or as catalyst for chemical process for degradation or transformation of organic substances or gases, for production of coating in combustion- motors or machines for motor interior area, pistons, exhaust gas- plant and diesel particle filter, on discs, machine parts, tubes or power stations, in fireplace inner rooms and combustion chambers, for glass- and steel inserts and/or chimney bricks and filter mats, as purification aid, in power station, on grill device, on baking oven, household utensils, ceramic boiler plate as antispatter, on a carrier for receiving organic component on the indoor air after absorption of the coating or for catalyst of chemical oxidation process for industrial use, in fuel cell for removing gaseous impurities of carbon monoxide, as catalyst for the energy extraction through catalytic splitting of water in hydrogen and oxygen (all claimed).    ADVANTAGE - The method ensures simple and efficient production of alkali- and alkaline earth alloys with good quality.    DETAILED DESCRIPTION - The method comprises mixing salts, hydroxides, alkoxides or oxides of alkali- or alkaline earth compounds with salts, hydroxides, alkoxides or oxides of semi-metals, nonmetals or metals and then heating at 100 degrees C. The salts, hydroxides, alkoxides or oxides of alkali- or alkaline earth metals are present in a molar ratio of 1:1 or in excess in relation to the salts, hydroxide, alkoxides or oxides of the semi-metals, nonmetals or metals. The salts, hydroxides, alkoxides or oxides of alkali- or alkaline earth compounds are alkali- or alkaline-earth sulfates, chlorides, nitrates, carbonates, formates, oxalates, sulfides, sulfites, bromides, iodides, fluorides, nitrides, nitrites, phosphates, phosphides, phosphites and acetates. The salts, hydroxides, alkoxides or oxides of semi-metals, nonmetals or metals are carbon dioxide, carbon monoxide, nitrogen trioxide, nitrogen pentoxide, nitrogen oxide, silicon oxide, aluminum oxide, tellurium oxide, germanium oxide, antimony oxide, gallium oxide, vanadium oxide, manganese oxide, chromium oxide, titanium oxide, zirconium oxide, cerium oxide, lanthanum oxide, cobalt oxide, copper oxide, iron oxide, silver oxide, tungsten oxide and zinc oxide. The salts, hydroxides, alkoxides or oxides of alkali- or alkaline compounds are mixed with the oxides of metals, semi-metals or nonmetals in the melt in the gas phase under increased pressure or as fluid coating materials in water. The metals, semi-metals or non-metals exist as oxides. The heating is carried out at 400 degrees C up to melting temperature of the high-melted components in 24 hours in oxygen-free atmosphere. The production of the alkali- and alkaline earth alloys as fluid coating materials is carried out after the sol-gel-process or over precipitation reactions directly from the elements through solid body reactions, flame pyrolysis or gas phase separations such as chemical vapor deposition or physical vapor deposition, through spray drying or freeze-drying. The salt of the alkali- or alkaline earth compounds is present on a ceramic solid body consisting of salts of semi-metals, nonmetals or metals and the temperature treatment is carried out at 200 degrees C.
