Metallurgical special alloys, rare earth metals or fluorides, silicides participate in steel, can play the role of essence, desulfurization, neutralization and low melting point harmful impurities, and can improve the processing of steel; rare earth ferrosilicon alloy, rare earth silicon magnesium alloy as The spheroidizing agent produces rare earth ductile iron, which is uniquely used for the production of messy ductile iron parts with special requirements. It is widely used in mechanical operations such as automobiles, tractors, diesel engines, etc.; rare earth metals are added to magnesium, aluminum, copper, Among the non-ferrous alloys such as zinc and nickel, the physical and chemical functions of the alloy can be improved, and the mechanical properties of the alloy at room temperature and high temperature can be improved.

 

In the military, rare earth is known as the “golden” industry. Because it has excellent physical properties such as light electromagnetic, it can successfully use various new materials with different varieties and other materials. The most obvious function is to greatly improve other products. Quality and function. For example, the tactical function of making steel for tanks, airplanes, missiles, aluminum alloys, magnesium alloys, and titanium alloys has been greatly improved. Moreover, rare earths are also many high-tech lubricants such as electronics, lasers, nuclear industry, and superconductors. Once used in the military, rare earth technology will surely bring a leap in military technology. In a certain sense, the US military overwhelmingly manipulated several local wars after the infighting, and was able to unscrupulously expose the slaughter to the enemy, which is due to the superhuman in the field of rare earth technology.

 

The molecular sieve catalyst made of rare earth with chemical activity has the advantages of high activity, good selectivity and strong resistance to heavy metal poisoning, thus replacing the aluminum silicate catalyst for the petroleum catalytic cracking process; in the process of composing ammonia production, a small number Rare earth nitrate is a cocatalyst, and its disposal gas volume is 1.5 times larger than that of nickel-aluminum catalyst. In the process of composition of butadiene rubber and isoprene rubber, the rare earth-triisobutyl aluminum type catalyst of naphthenic acid is selected, and the obtained product has excellent functions. The utility model has the advantages of less equipment hanging glue, stable work and short post-treatment steps; the composite rare earth oxide can also be used as a catalyst for exhaust gas purification of an internal combustion engine, and the naphthenate is also used as a paint drier.

 

Glass ceramic rare earth oxide or processed rare earth concentrate can be widely used as polishing powder for the polishing of optical glass, spectacle lenses, picture tubes, oscilloscope tubes, flat glass, plastic and metal tableware; in the process of melting glass, The cerium oxide can be used to have a strong oxidizing effect on iron, and the iron content in the glass is lowered to reach the green color in the glass; the addition of the rare earth oxide can produce different optical glass and special glass, including It can pass infrared rays, ultraviolet light absorbing glass, acid and heat resistant glass, X-ray resistant glass, etc.; adding rare earth in ceramic glaze and enamel can reduce the fragrant cracking of the glaze and make the product appear different colors. And luster, is widely used in the ceramic industry.
