Product features:
The physical and chemical properties of cerium oxide are greatly dependent on its own microstructure, such as particle size, crystal form, specific surface area, etc. The cerium oxide material with nano-scale porous structure can not only meet the requirements of high-efficiency adsorption materials for its own microstructure, but also increase the surface catalytic active sites by increasing the specific surface area, thereby improving the catalytic performance of cerium oxide.
The normal particle size of cerium oxide is D50: 15-22um, we can produce multiple particle size CeO2, such as 50nm, 50-100nm, 100-200nm, 0.5-1um, 2-3um, and big than 50um particle size cerium oxide.
The normal specific surface area of cerium oxide is 2-10m2/g, we can produce multiple specific surace area CeO2, such as <2m2/g, >50m2/g >80m2/g cerium oxide.
The normal specific gravity of cerium oxide is 7.1g/cm3, bulk density is 1.2-1.3kg/m, we can produce cerium oxide with a specific gravity more than 1.5
Applications: Cerium Oxide mainly used for glass precipitating and decoloring agents, also used in ceramic and electronic and catalysis industries, as the raw material of producing Ce metal and cerium oxide polishing powder.
Storage: Keep sealed and store in dry and cool places
Packing: Plastic woven bag inner with plastic bag. Net weight 25/50 kg
