Lanthanum(La)Oxide
Lanthanum Oxide, also known as a highly insoluble thermally stable Lanthanum source, is an inorganic compound containing the rare earth element lanthanum and oxygen. It is suitable for glass, optic and ceramic applications, and used in some ferroelectric materials, and is a feedstock for certain catalysts, among other uses.

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.

Lanthanum(III) Chloride
Lanthanum(III) Chloride Heptahydrate is an excellent water soluble crystalline Lanthanum source, which is an inorganic compound with the formula LaCl3. It is a common salt of lanthanum which is mainly used in research and compatible with chlorides. It is a white solid that is highly soluble in water and alcohols.
-
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.
