General description

Zirconium(IV) tert-butoxide, electronic grade (99.999% trace metals basis), is a high-purity, moisture-sensitive organometallic compound widely used as a catalyst and as a precursor for solution and vapor deposition processes, especially in the fabrication of energy materials and advanced ceramics. Its exceptional purity makes it ideal for applications in microelectronics, catalysis, and the synthesis of high-performance inorganic materials.

Application

Zirconium(IV) tert-butoxide can be used as:
  • A precursor in sol-gel processes to synthesize porous zirconia, which is widely used for catalyst supports and advanced materials applications.
  • A precursor that enables the efficient deposition of high-purity zirconium oxide thin films under atmospheric pressure plasma conditions, making it suitable for advanced electronic and optical applications.
  • A precursor in the green synthesis of N/Zr co-doped TiO₂ nanoparticles for enhanced photocatalytic degradation of p-nitrophenol (PNP).

Features and Benefits

  • High Purity and Low Total Metallic Impurities: Suitable for sensitive applications due to low impurity content and absence of residual chloride
  • Moisture Sensitivity: Highly sensitive to moisture; must be handled under inert atmosphere
  • Reactivity: Readily hydrolyzes to form zirconia (ZrO₂) or mixed oxides
