Cerium zirconium lanthanum praseodymium solid for automobile exhaust Ce30Zr60L5Y5
Lanthanum oxide is an odorless, white solid that is insoluble in water, but soluble in dilute acid. Depending on the pH of the compound, different crystal structures can be obtained.[citation needed] La2O3 is hygroscopic; under atmosphere, it absorbs moisture over time and converts to lanthanum hydroxide. Lanthanum oxide has p-type semiconducting properties and a band gap of approximately 5.8 eV..Its average room temperature resistivity is 10 kΩ·cm, which decreases with an increase in temperature.
【Application】
(1) Catalysis of automobile and motorcycle exhaust gas;
(2) Industrial organic waste gas purification and indoor air purification;
(3) Natural gas combustion catalysis.
(4) Fluid catalytic cracking in oil refining industry.
【Specification】
| ITEM | INDEX | ITEM | INDEX |
| CeO2% | 40% | D50 | 2.5-3.5um |
| ZrO2% | 50% | Fresh BET | >60-85m2/g |

【Product features】
(1) high temperature resistance and high aging ability: using cerium oxide and zirconia solid solution as the matrix, some additives (lanthanum oxide, yttrium oxide, praseodymium oxide, neodymium oxide) are added to replace the elements, which improves the high-temperature anti-aging ability of the products.
(2) Excellent oxygen storage and release capacity: the product has higher oxygen storage and release rate, faster oxygen storage and release rate and lower light off temperature
(3) Moderate particle size distribution: the medium diameter of the material is controlled to be 2.5-3.5 μ m by using air grinding and precise grading technology, and the particle size distribution is narrow, which improves the coating quality and reduces the peeling off rate.
【Packing】 25kgs/poly-drum ,500kgs/pallet
