Description |
Lanthanum cerium carbonate is a colorless granular crystal in appearance. It is soluble in water and alcohol and deliquesces easily in the humid air. |
|
Uses |
Lanthanum-cerium carbonate is used as a precursor for catalysts in automotive catalytic converters and industrial processes. The combined rare earth elements enhance the catalytic activity and thermal stability of the final catalyst. In the glass and electronics industries, lanthanum-cerium carbonate is used to produce cerium-based polishing powders, which provide efficient and high-quality polishing for optical lenses and semiconductor wafers. |
| Precipitation |
Lanthanum-cerium carbonate can be synthesized by precipitating the mixed rare earth elements from their chloride or nitrate solutions using a carbonate source such as sodium carbonate or ammonium carbonate. The precipitation conditions, such as pH and temperature, are carefully controlled to achieve the desired composition and purity. |
The single-step conversion of methane to methanol (MTM) represents an attractive route for the valorization of low-concentration coalbed methane (CBM). In this work, the effects of surface reactive oxygen and carbonate species on the catalytic performance of LaCeOx materials for MTM reaction was investigated.
Dispersion stability is a critical issue for the application of micron lanthanum-cerium-based slurry in liquid crystal display and other fields. Sodium hexametaphosphate (SHMP) is a commonly used dispersant, but there are problems that the dispersion mechanisms are not very detailed and the statements are inconsistent which are reported in the previous literature.
