Description

Indium Nitrate is a versatile inorganic salt widely used as a high-purity precursor in advanced material synthesis and electronics manufacturing. Its primary value lies in providing a soluble source of indium ions for the production of specialized compounds and thin-film coatings. This product is essential for industries focused on research and development, semiconductor fabrication, and the creation of transparent conductive oxides (TCOs).

Application

• Electronics & Semiconductor Manufacturing: Key precursor for depositing indium-containing thin films via chemical vapor deposition (CVD) or sol-gel processes, used in displays and photovoltaic cells.
• Catalyst Synthesis: Serves as a starting material for preparing indium-based catalysts used in organic synthesis and petrochemical reactions.
• Research & Development: Used in academic and industrial labs for synthesizing novel indium compounds, metal-organic frameworks (MOFs), and other advanced materials.
• Electroplating & Surface Treatment: Provides an indium source for specialized electroplating baths to create corrosion-resistant or solderable coatings on various substrates.
• Ceramic & Glass Production: Acts as a dopant or additive to modify the electrical or optical properties of specialty ceramics and glasses.
• Chemical Analysis: Utilized as a standard or reagent in analytical chemistry for calibration and testing procedures.

Quality Control

Our Indium Nitrate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high chemical purity. We provide comprehensive quality assurance, including testing for purity, heavy metal content, and other critical impurities relevant to electronic and research applications. A Certificate of Analysis (COA) detailing all test results is available for every batch upon request, supporting your compliance and traceability requirements.

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 should be handled in a dry environment to prevent caking or decomposition. For long-term storage, consider using desiccants or an inert atmosphere to minimize oxidation and moisture uptake.
