MEL Chemicals is one of the world’s leading producers of zirconium chemicals for catalyst applications. Zirconium compounds are used in a wide range of chemical reactions including isomerization, reduction, reforming, hydrogenation, oxidation, HDS/HDN, polymerization and environmental applications. Visit our web site for comprehensive reference information on the use of zirconia in catalysis.
The consumption of zirconium oxide, or zirconia, in the emission control catalyst technology has increased significantly over the last few years. Ceria doped zirconia has become a standard component of automotive three-way catalyst washcoats. Zirconia is also used in diesel catalysts for DOC and SCR applications and is actively researched as a prospective compound of lean NOx trap catalysts for both diesel and gasoline engines.
Zirconia is used in several other diesel and automotive applications including oxygen and NOx sensors and piezoelectric sensors.
MEL Chemicals is able to offer the widest range of zirconium chemicals suitable for catalysis. Our products include highest purity zirconias both undoped and doped with selected metal oxides for increased surface area and thermal stability. Customized products are available.
