Overview
Calcium nitride (Ca3N2) is an inorganic compound consisting of calcium and nitrogen, typically produced through direct reaction of calcium metal with nitrogen gas at high temperatures. The nanoscale powder form enhances its reactivity and suitability for advanced material synthesis. As a niche chemical, it finds specialized applications in materials science due to its ability to serve as a nitrogen source in ceramic production and its role in luminescent materials. Industrial-grade material typically ranges from micron to nanometer particle sizes.
Physical and Chemical Properties
Calcium nitride powder exhibits a cubic crystal structure at room temperature, transitioning to hexagonal form above 700°C. Its notable exothermic reaction with water produces calcium hydroxide and ammonia gas, requiring careful handling. The material demonstrates semiconductor properties with a bandgap of approximately 2.1 eV. Thermal decomposition occurs above 1,200°C under nitrogen atmosphere. Nanoscale variants show increased surface area (typically 20-100 m²/g for nanopowders), enhancing reactivity in synthesis applications.
Main Applications
In materials engineering, calcium nitride serves as a precursor for producing advanced nitride ceramics like silicon aluminum oxynitride (SiALON). The electronics industry utilizes it in thin film deposition processes for semiconductor devices. Phosphor manufacturers employ high-purity Ca3N2 as a host material for europium-doped red-emitting phosphors. Research applications include solid-state nitrogen storage and battery electrode materials development. Emerging uses involve photocatalytic systems and hydrogen storage materials.
Safety and Storage
Calcium nitride powder requires strict moisture control, ideally stored under argon or nitrogen in sealed containers. Exposure to humid air causes gradual hydrolysis, potentially leading to pressure buildup in improperly sealed packages. Personal protective equipment (PPE) including nitrile gloves, dust masks, and eye protection is mandatory during handling. Spills should be contained with dry absorbents and disposed as hazardous waste. Proper ventilation is essential to prevent ammonia gas accumulation from accidental hydrolysis.
B2B Procurement Guide
Industrial buyers should specify purity grade (99%, 99.5%, or 99.9%), particle size distribution (standard 1-10μm or nano 50-100nm), and packaging requirements (argon-filled bags or sealed drums). Technical datasheets should include XRD purity analysis and BET surface area for nanopowders. Lead times vary significantly (2-8 weeks) depending on customization requirements. Sample quantities (100g-1kg) are commonly available for testing. Consider supplier certifications for ISO 9001 and hazardous material handling when evaluating vendors.
