Lanthanum oxide is widely used and dopants are one of the important application fields.

Lanthanum oxide, with the chemical formula La2O3, also known as lanthanum trioxide, is an inorganic compound composed of lanthanum element and oxygen element, and is an important rare earth metal oxide. Lanthanum oxide appears as white powder, insoluble in water and ketones, but soluble in ethanol, ammonium chloride, and inorganic acids. When exposed to the air, it can absorb carbon dioxide and water to form lanthanum carbonate.

Lanthanum (La), a rare earth metal element, has a silvery gray luster, soft texture, and active chemical properties. Among the 17 rare earth elements, lanthanum is relatively abundant in the earth’s crust. The ore containing lanthanum is mainly bastnaite, also known as monazite. Its composition contains 20%-30% lanthanum oxide, which can be extracted through get. Monazite often forms placer deposits. Globally, monazite reserves are abundant in seaside placers in Australia, Brazil, and India. In my country, the Bayan Obo mining area in Inner Mongolia is an important source of monazite, but its taste is poor.

Lanthanum oxide has a wide range of uses and can be used as raw materials/intermediates, dopants, catalysts, analytical reagents, etc. to manufacture optical glass, optical fibers, luminescent materials, ceramic capacitors, piezoelectric ceramics, special alloys, refractory materials, high-temperature ultrasonic Guide materials, developers, medicines, high molecular polymers, dyes and other products are widely used in glass, ceramics, electronics, electric power, metallurgy, chemical industry, new materials, medical care, textiles, transportation, petroleum and other industries.

According to the “2023-2027 Lanthanum Oxide Industry In-depth Market Research and Investment Strategy Suggestion Report” released by the Industrial Research Center, doping Agents are an important application field of lanthanum oxide. In the chemical industry, new materials and other industries, the role of doping is to improve the properties of substances or materials, such as mechanical properties, photoelectromagnetic properties, etc., in order to increase the application value of substances or materials or broaden their application scope. For example, doping lanthanum oxide in sodium bismuth titanate (BNT) lead-free piezoelectric ceramics can improve piezoelectric activity; doping lanthanum oxide in titanium dioxide nanotube photocatalytic materials can improve catalytic activity; doping aluminum oxide Hybrid lanthanum oxide can improve thermal stability and inhibit high-temperature phase transition.

In overseas markets, the main lanthanum oxide manufacturers include American Elements, Edgetech Industries LLC, etc.; in the Chinese market, the main lanthanum oxide-related manufacturers include China Minmetals Corporation, Ganzhou Rare Earth Group Co., Ltd., Ganzhou Chenguang Rare Earth New Materials Co., Ltd., Longnan Longyttrium Heavy Rare Earth Technology Co., Ltd., Qiandong Rare Earth Group Co., Ltd., Inner Mongolia Baogang Hefa Rare Earth Co., Ltd., etc.

Industry analysts said that lanthanum oxide, as a rare earth metal oxide, plays an important role and has a wide range of uses, especially for doping. The agent can be widely used in the manufacturing of piezoelectric ceramics, optical crystals, special alloys, high-performance polymers and other products, and the market development prospects are broad. The element lanthanum has relatively large reserves in the earth’s crust. my country has monazite mineral resources. The supply of metal lanthanum in our country is relatively sufficient, which is conducive to the development of the lanthanum oxide industry.
