Description

Aluminum Nitrate Hydrate, Puratronic®, 99.999% (Metals Basis Excluding Hg) is an ultra-high-purity inorganic salt essential for advanced materials synthesis and precision manufacturing. This exceptional purity level, certified on a metals basis excluding mercury, is critical for applications where trace metallic impurities can compromise performance, yield, or product integrity. It is primarily required by industries involved in catalyst development, ceramic precursors, optical coatings, and high-purity alumina production. The product is identified by CAS No. 25838-59-9.

Application

• High-Purity Ceramic & Advanced Material Precursors: Serves as a key aluminum source for synthesizing specialty aluminas, transparent ceramics, and other high-performance oxide materials.
• Catalyst Synthesis & Research: Used in the preparation of supported and unsupported catalysts where ultra-pure aluminum compounds are required to avoid catalyst poisoning.
• Optical & Electronic Thin Films: Employed in chemical vapor deposition (CVD), atomic layer deposition (ALD), and sol-gel processes for creating optical coatings and semiconductor layers.
• Laboratory Reagent & Analytical Standards: Acts as a primary standard or high-purity reagent in analytical chemistry and trace metal analysis.
• Pharmaceutical & Fine Chemical Intermediates: Utilized in controlled synthesis processes where stringent purity specifications are mandated.
• Specialty Glass & Luminescent Materials: Functions as a dopant or matrix component in the production of specialty glasses and phosphors.

Quality Control

This Puratronic® grade product is manufactured under controlled conditions to meet the stringent 99.999% (Metals Basis Excluding Hg) purity specification. Quality is assured through advanced analytical techniques including Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Optical Emission Spectrometry (ICP-OES). A comprehensive Certificate of Analysis (COA) detailing trace metal impurities and other critical parameters is provided with each batch to ensure compliance with your research and manufacturing protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong oxidizer. Keep container tightly sealed to prevent absorption of moisture and store separately from combustible materials, reducing agents, and strong acids.
