Industrial Grade Calcium Cyanamide (Nitrolim) CAS 156-62-7 Fertilizer & Defoliant & Steel Desulfurizer

Calcium Cyanamide (Common Name: Lime Nitrogen, CAS:156-62-7,EINECS:205-861-8, HS Code:3102901000) is a versatile inorganic compound produced by reacting calcium carbide with nitrogen gas at high temperature. We provide agricultural grade and industrial grade products that conform to GB/T 2440-2017, FCC and international quality standards. It appears as gray-black powder or granular solid with a slight ammonia-like odor, featuring good chemical stability and slow-release nitrogen properties. With multiple functions as fertilizer, soil disinfectant, herbicide and chemical intermediate, it is widely applied in agriculture, chemical industry, metallurgy and environmental protection fields.

Applications
Agricultural Industry (Core Application)
Slow-release nitrogen fertilizer: Hydrolyzes in soil to release cyanamide, then converts to urea for plant absorption
Soil disinfectant: Suppresses soil-borne pathogens (fungi, bacteria, nematodes) and weed germination
Cotton defoliant: Promotes uniform leaf abscission for mechanical harvesting
Fruit tree dormancy breaker: Accelerates bud break and improves flowering uniformity
Alkaline soil conditioner: Adjusts pH value and improves soil structure
Chemical Industry (Key Application)
Primary raw material for dicyandiamide (DCD) production via hydration reaction
Intermediate for melamine, guanidine salts and thiourea synthesis
Precursor for calcium cyanide, cyanuric acid and other nitrogen-containing compounds
Catalyst and curing agent in polymer manufacturing processes
Metallurgical Industry
Desulfurization agent in steel production: Reacts directly with sulfur impurities in molten metal
Reducing agent for metal oxide reduction in non-ferrous metal smelting
Refining agent for removing phosphorus and other harmful elements from alloys
Other Industrial Applications
Environmental Protection: Used in wastewater treatment for removing heavy metals and organic pollutants
Rubber Industry: Vulcanization accelerator and reinforcing agent for rubber products
Adhesive Industry: Curing agent for phenol-formaldehyde and urea-formaldehyde resins
Mining Industry: Flotation agent for mineral processing and metal extraction
