Lanthanum carbonate, La 2 (C O 3) 3, is the salt formed by lanthanum(III) cations and carbonate anions. It is an ore of lanthanum metal ( bastnäsite ), along with monazite . Chemistry
Lanthanum carbonate – La 2 (CO 3) 3; Lanthanum magnesium – LaMg; Lanthanum manganite – LaMnO 3; Lanthanum mercury – LaHg; Lanthanum silver – LaAg; Lanthanum thallium – LaTl; Lanthanum zinc – LaZn; Lanthanum boride – LaB 6; Lanthanum carbonate – La 2 (CO 3) 3; Lanthanum(III) chloride – LaCl 3; Lanthanum trifluoride – LaF 3 ...
Modern uses of lanthanum include: LaB 6 hot cathode. One material used for anodic material of nickel–metal hydride batteries is La(Ni 3.6 Mn 0.4 Al 0.3 Co 0.7). Due to high cost to extract the other lanthanides, a mischmetal with more than 50% of lanthanum is used instead of pure lanthanum. The compound is an intermetallic component of the AB ...
It can be prepared by the reaction of lanthanum alkoxide and acetylacetone. [6] Its tetrahydrate decomposes into monohydrate at 110 °C, obtains the anhydrous form at 150 °C, undergoes La(CH 3 COO)(acac) 2 and La(CH 3 COO) 2 (acac), and at 180~285 °C lanthanum acetate is produced. [7] It can be used to prepare NaLaS 2, La 2 Zr 2 O 7 and other ...
Lanthanum acetate is an inorganic compound, a salt of lanthanum with acetic acid with the chemical formula La(CH 3 CO 2) 3. According to X-ray crystallography, anhydrous lanthanum acetate is a coordination polymer. Each La(III) center is nine-coordinate, with two bidentate acetate ligands and the remaining sites occupied by oxygens provided by ...
The CuTi 2 structure of the lanthanum, cerium and praseodymium diiodides along with HP-NdI 2 contain 4 4 nets of metal and iodine atoms with short metal-metal bonds (393-386 La-Pr). [10] these compounds should be considered to be two-dimensional metals (two-dimensional in the same way that graphite is). The salt-like dihalides include those of ...
L. Lanthanide trichloride; Lanthanum acetate; Lanthanum acetylacetonate; Lanthanum aluminate; Lanthanum barium copper oxide; Lanthanum carbide; Lanthanum carbonate
The anhydrous compound can be produced by heating the hydrates to 300 °C. If heated further, anhydrous lanthanum(III) sulfate decomposes to La 2 O 2 SO 4 at 775 °C, which in turn decomposes to lanthanum(III) oxide at 1100 °C.
