Description

Zirconium(IV) Ethoxide is a versatile metal-organic compound widely used as a precursor in advanced materials synthesis. This high-purity alkoxide is critical for depositing zirconium oxide (zirconia) thin films with exceptional dielectric, thermal, and chemical resistance properties. It is an essential raw material for manufacturers and R&D facilities in the electronics, optics, and specialty ceramics sectors seeking to enhance product performance through precise surface engineering.

Application

• Sol-Gel Processing & Thin Film Deposition: A key precursor for producing high-quality zirconia (ZrO₂) coatings via chemical solution deposition (CSD), spin-coating, or dip-coating techniques.
• Advanced Ceramics & Composites: Used in the synthesis of nano-sized zirconia powders and as a sintering aid for producing high-strength, wear-resistant technical ceramics.
• Microelectronics & Semiconductor Fabrication: Serves as a high-k dielectric material precursor for gate oxides in transistors and capacitor layers in memory devices (e.g., DRAM).
• Optical & Protective Coatings: Employed to create anti-reflective, scratch-resistant, and environmentally protective coatings on glass, lenses, and sensitive optical components.
• Catalyst & Catalyst Support Synthesis: Acts as a catalyst precursor or a modifying agent to create supports with tailored acidity and thermal stability for heterogeneous catalysis.
• Surface Modification & Cross-linking Agent: Utilized to functionalize surfaces of polymers or other materials, improving adhesion, hardness, and chemical resistance.

Quality Control

Our Zirconium(IV) Ethoxide is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the exacting requirements of advanced materials applications. A detailed Certificate of Analysis (COA) providing specifications for assay, impurity profiles, and physical properties is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to maximize shelf-life stability. Always handle in a controlled, moisture-free environment.
