Lutetium(III) Oxide

Lutetium(III) Oxide (Lu2O3), also known as lutecia, is a white solid and a cubic compound of lutetium. It is a highly insoluble thermally stable Lutetium source, which has a cubic crystal structure and available in white powder form. This rare earth metal oxide exhibits favorable physical properties, such as a high melting point (around 2400°C), phase stability, mechanical strength, hardness, thermal conductivity, and low thermal expansion. It is suitable for specialty glasses, optic and ceramic applications. It is also used as the important raw materials for laser crystals.
Lanthanum Hexaboride

Lanthanum Hexaboride (LaB6, also called lanthanum boride and LaB) is an inorganic chemical, a boride of lanthanum. As refractory ceramic material that has a melting point of 2210 °C, Lanthanum Boride is highly insoluble in water and hydrochloric acid, and converts to the oxide when heated (calcined). Stoichiometric samples are colored intense purple-violet, while boron-rich ones (above LaB6.07) are blue. Lanthanum Hexaboride (LaB6) is known for its hardness, mechanical strength, thermionic emission, and strong plasmonic properties. Recently, a new moderate-temperature synthetic technique was developed to directly synthesize LaB6 nanoparticles.
Holmium Oxide

Holmium(III) oxide, or holmium oxide is a highly insoluble thermally stable Holmium source. It is a chemical compound of a rare-earth element holmium and oxygen with the formula Ho2O3. Holmium oxide occurs in small quantities in the minerals monazite, gadolinite, and in other rare-earth minerals. Holmium metal easily oxidizes in air; therefore presence of holmium in nature is synonymous with that of holmium oxide. It is suitable for glass, optic and ceramic applications.
Europium(III) Oxide

Europium(III) Oxide (Eu2O3) is a chemical compound of europium and oxygen. Europium oxide has also other names as Europia, Europium trioxide. Europium oxide has a pinkish white color. Europium oxide has two different structures: cubic and monoclinic. The cubic structured europium oxide is almost same as magnesium oxide structure. Europium oxide has negligible solubility in water, but readily dissolves in mineral acids. Europium oxide is thermally stable material that has melting point at 2350 oC. Europium oxide’s multi-efficient properties like magnetic, optical and luminescence properties make this material very important. Europium oxide has an ability to absorb moisture and carbon dioxide in atmosphere.
Dysprosium Oxide

As one of the rare earth oxide families, Dysprosium Oxide or dysprosia with chemical composition Dy2O3, is a sesquioxide compound of the rare earth metal dysprosium, and also a highly insoluble thermally stable Dysprosium source. It is a pastel yellowish-greenish, slightly hygroscopic powder, which has specialized uses in ceramics, glass, phosphors, lasers.
Lanthanum Hydroxide

Lanthanum Hydroxide is a highly water insoluble crystalline Lanthanum source, which can be obtained by adding an alkali such as ammonia to aqueous solutions of lanthanum salts such as lanthanum nitrate. This produces a gel-like precipitate that can then be dried in air. Lanthanum hydroxide does not react much with alkaline substances, however is slightly soluble in acidic solution. It is used compatibly with higher (basic) pH environments.
Lanthanum Carbonate

Lanthanum Carbonate is a salt formed by lanthanum(III) cations and carbonate anions with the chemical formula La2(CO3)3. Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides.
Erbium Oxide

Erbium oxide (Er₂O₃) is a pink powdered rare earth oxide with stable chemical properties, excellent high-temperature resistance and thermal stability. Slightly hygroscopic, it should be stored in a sealed container. It is insoluble in water and slightly soluble in acids.

As a versatile rare earth functional material, erbium oxide plays an irreplaceable role in modern optoelectronic information, advanced manufacturing, environmental catalysis and other fields. It is widely used in optical fiber communication, laser devices, optical infrared materials, high-grade glass and ceramic coloring, up-conversion phosphors, special alloy modification and catalytic additives. It is a core rare earth raw material for optical communication, laser medicine, precision optics and advanced material manufacturing.

UrbanMines supplies custom-grade erbium oxide with typical purities of 99.9% (3N), 99.99% (4N) and higher grades. It features strict impurity control, excellent batch-to-batch consistency, and unique optical, luminescent and material-modifying properties to suit diverse applications.
Cerium Hydroxide

Cerium(IV) Hydroxide, also known as ceric hydroxide, is a highly water insoluble crystalline Cerium source for uses compatible with higher (basic) pH environments. It is an inorganic compound with the chemical formula Ce(OH)4. It is a yellowish powder that is insoluble in water but soluble in concentrated acids.
Thulium Oxide

Thulium(III) Oxide is a highly insoluble thermally stable Thulium source, which is a pale green solid compound with the formula Tm2O3. It is suitable for glass, optic and ceramic applications.
Samarium(III) Oxide

Samarium(III) Oxide is a chemical compound with the chemical formula Sm2O3. It is a highly insoluble thermally stable Samarium source suitable for glass, optic and ceramic applications. Samarium oxide readily forms on the surface of samarium metal under humid conditions or temperatures in excess of 150°C in dry air. The oxide is commonly white to off yellow in color and is often encountered as a highly fine dust like pale yellow powder, which is insoluble in water.
Terbium(III,IV) Oxide

Terbium(III,IV) Oxide, occasionally called tetraterbium heptaoxide, has the formula Tb4O7, is a highly insoluble thermally stable Terbium source.Tb4O7 is one of the main commercial terbium compounds, and the only such product containing at least some Tb(IV) (terbium in the +4 oxidation state), along with the more stable Tb(III). It is produced by heating the metal oxalate, and it is used in the preparation of other terbium compounds. Terbium forms three other major oxides: Tb2O3, TbO2, and Tb6O11.
