Application
合成烯烃官能化含锆单体的便捷前体，该单体可生成含锆的杂化聚合物。
- Zr(OEt)₄ can be used as a: Precursor in the sol-gel synthesis of PMMA/ZrO₂ hybrid. These films exhibit enhanced dielectric properties for flexible electronic applications.
- Precursor for the synthesis of Li₂ZrO₃ coatings on NCM622 particles.
- As a precursor in the synthesized of Zirconia nanoparticles (ZrO2NPs) by sol–gel reaction.
Features and Benefits
- The purity level (97%) influences the catalytic activity and selectivity, as higher purity typically leads to fewer side reactions and better control over synthesis of polymers.
- The purity and viscosity of the ethoxide can influence the uniformity and adhesion of the coatings, impacting their performance in various environments.
General description
Zirconium(IV) ethoxide is a colourless to pale yellow liquid widely used as a zirconium precursor. It is highly reactive toward moisture and well-suited for hydrolysis and condensation reactions. The compound is soluble in organic solvents such as alcohols and hydrocarbons, enabling its use in various solution-based synthesis techniques. It thermally decomposes into high-purity zirconium dioxide (ZrO₂), a valuable ceramic material known for its thermal stability, corrosion resistance, and dielectric properties. Zirconium(IV) ethoxide is commonly employed in sol-gel processes, chemical vapor deposition (CVD), and the synthesis of nanomaterials, facilitating the fabrication of uniform thin films, coatings, and advanced ceramic components. Its controlled reactivity, high volatility, and compatibility with diverse synthesis routes make it a versatile and efficient precursor for developing zirconium-based materials.
