Description

Calcium Phosphide is an inorganic chemical compound primarily used as a highly effective source of phosphine gas. This material is critical for industrial applications requiring a controlled, on-demand release of phosphine for fumigation and synthesis. It serves as a key raw material for industries including pest control, semiconductor manufacturing, and specialty chemical production, where reliable quality and consistent reactivity are paramount for process safety and efficacy.

Application

• Grain and Commodity Fumigation: As a solid source of phosphine gas for controlling insects and pests in stored agricultural products.
• Semiconductor Industry: Used in doping processes and as a precursor in the deposition of phosphorus-containing thin films.
• Rodenticide and Pest Control Formulations: Employed in the manufacturing of pellets or tablets for rodent and burrowing pest eradication.
• Organic Synthesis: Acts as a phosphiding or reducing agent in the preparation of various phosphorus-containing compounds.
• Signal and Incendiary Devices: Utilized in marine and military applications for the generation of smoke signals or flares.
• Laboratory Research: Serves as a reagent for studying phosphine chemistry and developing new catalytic processes.

Quality Control

Our Calcium Phosphide is manufactured under stringent process controls to ensure batch-to-batch consistency and high reactivity. Quality is verified through a series of analytical tests including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing purity, phosphine yield, and other critical parameters is provided with each shipment to guarantee it meets your specific technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area, away from moisture, acids, and oxidizing agents. Due to its hygroscopic and highly volatile nature, containers must be kept sealed under an inert atmosphere (e.g., argon or nitrogen) when not in use. Recommended storage temperature: 15-25°C.
