Product introduction
There are a dozen raw materials, metals or group of metals, are defined as critical materials for many important emerging technologies of its regional industries, highlighting their vulnerability, due to p shortages. It includes antimony, beryllium, cobalt, fluorspar, gallium, germanium, graphite, indium, magnesium, niobium, tantalum and tungsten and two groups of other elements: PGMs (platinum group metals, which include iridium, osmium, palladium, platinum, rhodium and ruthenium) and rare earths (REs) group.
The rare earth catalyst raw material are usually cerium and zirconia oxides solid with some additives (lanthanum oxide, yttrium oxide, praseodymium oxide, neodymium oxide and so on), they have huge specific surface area, more micropore, excellent oxygen storage and release capacity, high temperature resistance and high aging ability for the catalytic converter.
The rare earth catalyst raw material can help customers meet Euro5, Euro6, Tier and EPA emission standard.
