Description

Chromium Tris(2,2,6,6-Tetramethyl-3,5-Heptanedionate) is a high-purity, organometallic coordination compound where chromium is chelated by three 2,2,6,6-tetramethyl-3,5-heptanedionate (thd) ligands. This compound matters as a versatile and thermally stable precursor for depositing high-quality chromium and chromium oxide thin films via chemical vapor deposition (CVD) and atomic layer deposition (ALD) techniques. It is essential for manufacturers and R&D facilities in the semiconductor, optical coating, and advanced materials sectors who require precise control over film stoichiometry and properties.

Application

• Thin Film Deposition Precursor: A key source material for Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD) processes to create chromium, chromium oxide (Cr2O3), and mixed-metal oxide films.
• Semiconductor Manufacturing: Used in the fabrication of diffusion barriers, hard masks, and conductive layers in microelectronic devices and integrated circuits.
• Optical and Protective Coatings: Enables the deposition of durable, corrosion-resistant, and optically functional coatings on lenses, mirrors, and architectural glass.
• Catalyst Research: Serves as a catalyst or catalyst precursor in specialized organic synthesis and polymerization reactions.
• Nanomaterial Synthesis: Acts as a starting material for the sol-gel synthesis of chromium-containing nanoparticles and advanced ceramics.
• Surface Modification: Applied to modify surface properties of materials for enhanced wear resistance, adhesion, or specific chemical functionality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., argon or nitrogen) after initial opening to prevent degradation. Keep away from incompatible materials.
