Description

Indium Sulfate is a high-purity inorganic salt essential for advanced material synthesis and electroplating processes. Its primary value lies in providing a reliable source of indium(III) ions for applications demanding precise stoichiometry and minimal metallic impurities. This compound is particularly critical for manufacturers and R&D facilities in the electronics, semiconductor, and specialty glass industries. We supply it in various grades to meet both research-scale and industrial production requirements.

Application

• Electroplating Baths: Used as a key precursor for depositing indium and indium alloy coatings on various substrates, crucial for electronics and corrosion-resistant surfaces.
• Semiconductor Doping: Serves as a source material for introducing indium into compound semiconductors like InP and InGaAs for optoelectronic devices.
• Chemical Synthesis: Acts as a starting material or catalyst in the preparation of other indium compounds and complex inorganic materials.
• Specialty Glass & Ceramics: Employed as a dopant to modify the electrical and optical properties of specialty glasses and ceramic formulations.
• Research & Development: Utilized in academic and industrial labs for developing new materials, including phosphors, catalysts, and battery components.
• Analytical Reagent: Functions as a standard or reagent in analytical chemistry for quantitative analysis and calibration.

Quality Control

Our Indium Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the specified purity and impurity profile. We provide detailed Certificates of Analysis (COA) that include results for assay, identity, and key metallic impurities. Specifications can be aligned with customer-specific requirements for research, electronic, or industrial grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent absorption of moisture from the air. Long-term storage is recommended under controlled ambient conditions (15-25°C).
