About the usefulness of special alloys and rare earths

In metallurgy, special alloys, rare earth metals or fluorides and silicides can participate in the steel, which can play the role of refined, desulfurization, medium and low melting point harmful impurities, and can improve the processing function of the steel; Nodulizing agent produces rare earth nodular cast iron, because this nodular cast iron is uniquely suitable for producing cluttered nodular iron parts with special requirements, and is widely used in mechanical operations such as automobiles, tractors, diesel engines; Among nonferrous alloys such as zinc and nickel, the physical and chemical functions of the alloy can be improved, and the mechanical functions of the alloy at room temperature and high temperature can be improved.

Military rare earth is called the industrial "gold", because it has excellent optical and electromagnetic physical properties, and can successfully use different materials with a wide variety of new materials. Its most obvious function is to greatly improve other products. Quality and function. For example, the tactical functions of steel, aluminum alloy, magnesium alloy, and titanium alloy used to make tanks, aircraft, and missiles have been greatly improved. In addition, rare earths are also many high-tech lubricants for electronics, lasers, nuclear industries, superconductors, etc. Once the rare earth technology is used in the military, it will definitely bring a jump in military technology. In a certain sense, the overwhelming control of the US military in several local wars after the underground fight and its ability to expose the slaughter unscrupulously to the enemy are due to the superman in the field of rare earth technology.

Molecular sieve catalysts made of rare earths in terms of chemistry have the advantages of high activity, good selectivity, and strong resistance to heavy metal poisoning, so they have replaced aluminum silicate catalysts for the catalytic cracking of petroleum. In the process of ammonia production, a small number of Rare earth nitrate is a co-catalyst, and its disposal gas volume is 1.5 times larger than that of nickel-aluminum catalyst. In the process of composing butadiene rubber and isoprene rubber, a rare earth naphthenate-triisobutylaluminum type catalyst is selected, and the product function obtained is excellent. It has the advantages of less equipment hanging glue, stable work, short post-treatment process, etc .; the compound rare earth oxide can also be used as an exhaust gas purification catalyst for internal combustion engines, and cerium naphthenate can also be used as a paint drier.

Glass ceramic rare earth oxides or processed rare earth concentrates can be widely used as polishing powders for polishing optical glass, spectacle lenses, picture tubes, oscilloscopes, flat glass, plastics and metal tableware; in the process of melting glass, Can use cerium dioxide to have a strong oxidation effect on iron, reduce the iron content in the glass in order to reach the intention of removing green in the glass; increasing rare earth oxides can produce optical glasses and special glasses with different uses, including Can pass through infrared, ultraviolet-absorbing glass, acid-resistant and heat-resistant glass, X-ray-proof glass, etc .; adding rare earth to ceramic glaze and porcelain glaze can reduce the chipping of the glaze and make the product appear different colors And gloss are widely used in the ceramic industry.
