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 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.
Lutetium(III) Oxide

It is the most stable form of praseodymium oxide at ambient temperature and pressure.It is a highly insoluble thermally stable Praseodymium source suitable for glass, optic and ceramic applications. Praseodymium(III,IV) Oxide is generally High Purity (99.999%) Praseodymium(III,IV) Oxide (Pr2O3) Powder lately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered.
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.
Scandium Oxide

Scandium(III) Oxide or scandia is a inorganic compound with formula Sc2O3. The appearance is fine white powder of cubic system. It has different expressions like scandium trioxide, scandium(III) oxide and scandium sesquioxide. Its physico-chemical properties are very close to other rare earth oxides like La2O3, Y2O3 and Lu2O3. It is one of several oxides of rare earth elements with a high melting point. Based on present technology, Sc2O3/TREO could be 99.999% at highest. It is soluble in hot acid, however 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.
