Zirconium(IV) ethoxide, also known as Tetraethoxyzirconium or Zr(OEt)₄, is an organozirconium compound with the molecular formula C₈H₂₀O₄Zr and a molecular weight of 271.47 g/mol. This compound features zirconium in a +4 oxidation state, coordinated with four ethoxy ligands, forming a stable yet reactive complex ideal for use in synthesis. Zirconium(IV) ethoxide typically appears as off-white crystals or powder with a high purity level of 99%+, confirmed by elemental analysis, containing 34.8-35.6% carbon and 7.3-7.5% hydrogen. Its melting point range of 170–180°C supports its use in temperature-sensitive processes, although its high moisture sensitivity necessitates storage in sealed, moisture-free containers to prevent hydrolysis or decomposition.
Applications in Organic and Inorganic Synthesis
Zirconium ethoxide is a valuable reagent in both organic and inorganic synthesis, serving widely as a zirconium precursor in sol-gel processes and thin-film deposition applications. Its reactivity with water allows it to participate in controlled hydrolysis, facilitating the production of zirconium oxide films and high-performance ceramics. This controlled reactivity is particularly useful in microelectronics, where zirconium ethoxide helps create uniform, thin layers essential for electronic and semiconductor devices.
Precautions for Safe Storage and Handling
Zirconium(IV) ethoxide is classified as a flammable substance and requires careful handling. Personal protective equipment, including gloves, eye protection, and flame-resistant clothing, is recommended, particularly in well-ventilated areas. Due to its moisture sensitivity, the compound should be stored under an inert gas, such as nitrogen, in sealed containers to prevent exposure to moisture, which could trigger unwanted hydrolysis and compromise the compound’s integrity.
Industrial and Laboratory Applications
In both industrial and laboratory contexts, Zirconium(IV) ethoxide is essential for creating zirconium-based oxides and ceramics. Its use in thin-film deposition and sol-gel synthesis makes it invaluable for applications in material science, particularly in producing electronic components and protective coatings. The compound’s stability, high purity, and specific carbon and hydrogen content allow for precise control in advanced material fabrication, meeting the stringent requirements of high-tech and semiconductor applications.
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
