Description

Calcium Hydride is a powerful inorganic reducing agent and desiccant, widely recognized for its high reactivity with water. Its ability to efficiently generate hydrogen gas and remove trace moisture makes it a critical material for demanding industrial processes. This compound is essential for manufacturers and researchers in sectors requiring ultra-dry conditions or controlled hydrogen production, such as metallurgy, fine chemical synthesis, and specialty gas purification.

Application

• Drying Agent: Used for drying inert gases and organic solvents to achieve extremely low moisture levels.
• Hydrogen Generation: Serves as a portable and controllable source of high-purity hydrogen gas for laboratory and industrial applications.
• Metallurgical Processing: Employed as a reducing agent in the production and purification of certain metals and alloys.
• Chemical Synthesis: Acts as a strong base and reductant in various organic and inorganic synthetic pathways.
• Gettering: Used in vacuum systems and electronic component manufacturing to scavenge residual oxygen and water vapor.
• Laboratory Reagent: Utilized in analytical chemistry and research for its specific desiccant and reductive properties.

Quality Control

Our Calcium Hydride is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. The product undergoes rigorous analytical testing, including assay and impurity profiling. A Certificate of Analysis (COA) detailing purity and key specifications is provided with each shipment and is available upon request to support your quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible materials such as acids and oxidizers. For long-term stability, storage under an inert atmosphere (e.g., argon or nitrogen) is recommended.
