National Oceanic and Atmospheric Administration. In all cases of accidental exposure to calcium cyanamide, call the Poison Control Center. Hypocalcemia, inhibition of calcium efflux, or blockade of calcium’s effects may cause muscle cramps, tetany, and ventricular fibrillation. Protective gloves, goggles and a breathing mask are required for those who work directly with calcium cyanamide. What is calcium citrate? Contact with acids causes rapid evolution of hydrogen cyanide. Examples of inorganic cyanides include: calcium cyanide, potassium cyanide, sodium cyanide, lead cyanide, potassium cyanide, and silver cyanide. Calcium is a mineral that is found naturally in foods. The chemical is applied directly to the soil, where it breaks down into ingredients that are beneficial to plan growth. In contact with water it decomposes and liberates ammonia: Cyanide can be released fro… In carbide: Ionic carbides …°C [1,800–2,200 °F]) to form calcium cyanamide, CaCN 2. New Window. Calcium cyanamide's primary function is that of a fertilizer in industrial agriculture settings. She also volunteers at an animal shelter and operates a home bakery. With the quantity commonly used this reaction continues for several hours. Adequate ventilation is extremely important when handling or applying the chemical. Gordex Minerals used a calcium cyanide solution to 'leach' gold from crushed rock excavated at Cape Spencer. May react rapidly with oxidizing agents. In addition to acting as a fertilizer, the chemical also functions as an effective pesticide and fungicide by killing insects, soil parasites and harmful fungi. "c" indicates that although not listed by name and CAS number, this chemical is reportable under one or more of the EPCRA section 313 chemical categories. (USCG, 1999), Inhalation or ingestion causes headache, nausea, vomiting and weakness; high concentrations are rapidly fatal. An English major, she continues to study information systems management at American Public University. Calcium cyanamide is also used in non-agricultural applications, such as the manufacture and refining process of iron and industrial chemical products. Uses of Calcium Nitrate Used in agriculture as a fertilizer and in match manufacture as an oxidizing agent. 7 Use and Manufacturing 7.1 Use Classification Calcium cyanamide is used as a fertilizer, pesticide, and in the manufacture of other chemicals. National Ocean Service, Calcium cyanide is a white-colored chemical with compound formula CA(CN) 2. This calcium derivative of cyanamide (CN 22−) is used as fertilizer. It was used to produce sodium cyanide by fusing with sodium carbonate: CaCN 2 + Na 2 CO 3 + 2 C → 2 NaCN + CaO + 2 CO. ... National... 7.3 Methods of Manufacturing Sodium amide is obtained by the reaction of ammonia with Na at 400°C. Properties. It was used to produce sodium cyanide by fusing with sodium carbonate, which was used in cyanide process in gold mining: CaCN 2 + Na 2 CO 3 → 2 NaCN + CaO + O 2 The chemical enriches the soil with beneficial lime and, upon coming into contact with water, begins to break down, releasing nitrogen into the soil by way of ammonia. Calcium cyanamide's primary function is that of a fertilizer in industrial agriculture settings. It is used in stainless steel manufacturing, leaching ores, as a fumigant, insecticide and a single dose poison. Incompatible with isocyanates, nitrides, and peroxides… (USCG, 1999). Calcium citrate is used to prevent and to treat calcium deficiencies. CaC 2 + N 2 → CaCN 2 + C This is an important industrial reaction because CaCN 2 finds extensive use as a fertilizer owing to its reaction with water to produce cyanamide, H 2 NCN.
