Zirconium(IV) ethoxide is a precursor for the synthesis of olefin-functionalized zirconium-containing monomers, which have the potential for the generation of hybrid zirconium-containing polymers. Zirconium alkoxides are widely applied as precursors for the growth of Zr-containing layers by MOCVD or ALD. See link below

Ereztech manufactures and sells this product in small and bulk volumes. Glass ampules, bottles or metal ampules or bubblers are available for packaging. For additional analytical information or details about purchasing ZR7088 contact us at sales@ereztech.com
