Description

Arsenolite CAS NO 1303-24-8 is the most common naturally occurring mineral form of arsenic trioxide (As₂O₃). This high-purity inorganic compound is a critical raw material and intermediate in several advanced industrial and research sectors. It is essential for manufacturers and R&D facilities requiring a reliable source of arsenic for synthesis, doping, and specialized applications. Key industries include electronics, metallurgy, and specialized chemical manufacturing.

Application

• Semiconductor Manufacturing: Used as a doping agent in gallium arsenide (GaAs) and other III-V semiconductor crystals.
• Glass Production: Acts as a fining agent to remove bubbles and as a decolorizer to counteract the green tint from iron impurities.
• Wood Preservation: A key component in the formulation of copper chrome arsenate (CCA) for pressure-treated lumber.
• Metallurgy: Employed in alloy production and as an additive to harden lead-based alloys for ammunition and bearings.
• Chemical Synthesis: Serves as a fundamental precursor for the manufacture of other arsenic compounds, including pharmaceuticals and pesticides.
• Research & Development: Utilized in analytical chemistry as a standard and in materials science research.
• Ceramics & Pigments: Used in the production of certain specialty ceramics and historical pigments.

Quality Control

Our Arsenolite is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We offer material suitable for industrial and technical applications, with specifications tailored to meet specific customer requirements. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong reducing agents and foodstuffs.
