Description

Barium Bis(2,2,6,6-Tetramethyl-3,5-Heptanedionate) Hydrate is a high-purity metal-organic coordination compound, specifically a barium β-diketonate complex. This material serves as a critical precursor for depositing barium-containing thin films via chemical vapor deposition (CVD) and atomic layer deposition (ALD) techniques. It is essential for manufacturers and R&D facilities in the electronics, optics, and advanced ceramics sectors requiring precise, high-performance barium oxide coatings. The compound's properties make it suitable for applications demanding controlled stoichiometry and excellent film uniformity.

Application

• Thin Film Deposition: A key precursor for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) processes to produce barium titanate (BaTiO3) and other barium-based oxide films for capacitors and ferroelectric devices.
• Electronics Manufacturing: Used in the fabrication of multilayer ceramic capacitors (MLCCs), piezoelectric sensors, and non-volatile memory elements.
• Optical Coatings: Serves as a source material for creating high-refractive-index layers and specialized optical filters.
• Superconductor Research: Employed as a precursor in the development of high-temperature superconducting films, such as YBCO (Yttrium Barium Copper Oxide).
• Catalysis: Acts as a catalyst or catalyst precursor in specialized organic synthesis and polymerization reactions.
• Research & Development: A valuable reagent for academic and industrial research in materials science, solid-state chemistry, and surface science.

Quality Control

Our Barium Bis(2,2,6,6-Tetramethyl-3,5-Heptanedionate) Hydrate is produced under controlled conditions to ensure high purity and batch-to-batch consistency suitable for advanced material synthesis. Each lot undergoes rigorous analytical testing, including assay, metal content analysis, and identification of key impurities. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and trace metal content is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and must be handled in a dry, inert atmosphere (e.g., glovebox) or under anhydrous conditions to prevent decomposition. For long-term storage, consider sealing under an inert gas such as argon or nitrogen.
