High temperature stability of today's catalysts was made possible by the discovery of synergistic effects between zirconia and the traditional catalyst washcoat materials, such as aluminum oxide and cerium oxide. Zirconia is also used in diesel catalyst applications and actively researched as a prospective compound of the lean NOx catalyst for both diesel and gasoline engines. Zirconia is used in several other diesel and automotive applications including thermal management in-cylinder engine coatings which were shown to reduce diesel emissions, oxygen sensors and piezoelectric sensors. MEI - 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.
