The calcium carbide is one of the most commonly used ripening agent for fruits, while other calcium salts like calcium ammonium nitrate, calcium chloride and calcium sulfate are used to delay fruit ripening agents for local fruit industries. The use of calcium carbide is being discouraged worldwide, due to associated health hazards.
In order to create an explosion, using Calcium Carbide, you''ll need the following: calcium carbide, water, a dropper, and a lighter. Place a small chunk of calcium carbide in a petri dish. Fill the dropper with water. Light the lighter and hold it close to the calcium carbide, while you drop a drop of water onto the calcium carbide. Pull the dropper back immediately.
Safety Data Sheet according to 29CFR1910/1200 and GHS Rev. 3 Effective date : Page 1 of 7 Calcium Carbide Created by Global Safety Management, Inc. Tel:
Improved desulfurization of ferrous melts is obtained by injecting into the melt in finely divided form a mixture by weight 48% to 95% calcium carbide, 2% to 40% of carboncontaining calcium carbonate and from about 1% to 12% of high volatile, bituminous coal dust.
Calcium carbide residue is the waste produced when calcium carbide reacts with water in the generator in the process of producing PVC in chloralkali chemical industry to produce acetylene carbide slag can be used to produce cement, which is the most effective way to dispose calcium carbide, using calcium carbide slag ...

Calcium Carbide is a FLAMMABLE AND REACTIVE SOLID. When Calcium Carbide is exposed to WATER or MOISTURE it forms flammable Acetylene gas. Use approved Class D extinguishers or smother with dry sand, dry clay or dry ground limestone. DO NOT USE WATER, CO 2 or as extinguishing agents. POISONOUS GASES ARE PRODUCED IN FIRE, including
The resulting calcium sulfite collects at the base of the absorber and compressed air is blown into this residue. The calcium sulfite reacts with the air to form calcium sulfate (gypsum), used to make, for example, plaster board and cement. Very fine and pure calcium carbonate is used as filler in .
Manufacturers make calcium hydroxide by mixing water and calcium oxide. It dissolves more rapidly than ground limestone when used in landscaping but is more expensive. Slaked lime has several different common names depending on its particular use. As construction lime, builders use the material to plaster walls and to stabilize road beds.

PDF | Calcium carbide residue mainly composed of Ca(OH)2 can be used in wet flue gas desulfurization (FGD). Different from the traditional limestone–gypsum wet FGD, calcium carbide .
Calcium carbide, when coming across with water or steam, generates acetylene and release a large amount of heating. CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 +, 1kg of pure calcium carbide can produce 366 L of acetylene 366l (15 ℃, ). Thereby, for its storage: calcium carbide should be strictly kept away from water.
Commonly known as nitrolime, calcium cyanamide is used as fertilizer. It is hydrolysed to cyanamide, H 2 NCN. Steelmaking. Calcium carbide is used: in the desulfurization of iron (pig iron, cast iron and steel) as a fuel in steelmaking to extend the scrap ratio to liquid iron, depending on economics.
An agent for desulfurization, dephosphorization, desiliconizing, and denitriding of ironmelt and melt containing chromium or manganese, consisting of at least one of the following mineral rawmaterial: alkalicontaining plagioclase (feldspar), alkalicontaining orthoclase, montmorillonite (perlite), bentonite, muscovite, or zeolithe, and calcium carbide and/or calcium oxide.
Calcium carbide, when coming across with water or steam, generates acetylene and release a large amount of heating. CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 +, 1kg of pure calcium carbide can produce 366 L of acetylene 366l (15 ℃, ). Thereby, for its storage: calcium carbide should be strictly kept away from water.
Aug 18, 2019· This level decreases with time and experience, but often not to a level low enough so the waste could be considered nonreactive. Recent innovations in process control for calcium carbide desulfurization include methods of introducing the material itself as well as forms of the material. The most common form of calcium carbide used is coarse ...
Calcium carbide has the nominal formula of CaC 2 and the molecular weight of g/mol. The pure material is colorless, but most samples have a color ranging from black to grayishwhite, depending on the grade. Its density is g/cc and it melts at 2160 °C with a boiling point (under an inert atmosphere) of 2300 °C, where it decomposes.
Jul 03, 2005· Calcium Carbide CaC2 Acquisition, Uses and Synthesis Hallo to all, I''m looking for CaC2 in Italy, but I haven''t find anything. Is it today used? I don''t know, because acetylene lamps aren''t used today. Where and under what name I can buy it (except scientifical suppliers)? Thanx for help. [Edited on 392004 by chemoleo]
Product for desulfurization of liquid cast iron composed of technical calcium carbide powder, to which may be added products intended to cause gaseous release in the bath and to modify the composition of the slag and which is coated or agglomerated either by resins or an organic compound having a clearcut melting point and which is solid at ambient temperature.
Calcium carbide is also used as a desulfurizing agent in steel making and for the manufacture of calcium cyanamide. ... Desulfurization of the liquid and char products can be achieved by ...
CALCIUM CARBIDE is a reducing agent. May react vigorously with oxidizing materials. The powdered mixture of the acetylide and iron oxide and iron chloride burns violently upon ignition, producing molten iron. Calcium carbide incandesces with chlorine, bromine, or iodine at 245, 350, or 305°C., respectively, [Mellor, 1946, Vol. 5, 862].
Feb 16, 1982· Since the desulfurization slag has a solid, crumbly and partially dusty consistency when desulfurizing agents containing calcium carbide are used, the carbon contained in the slag escapes during the deslagging process with the rising hot air and forms black dust .
dust) containing no asbestos and <1% crystalline ... Inhaling Calcium Carbonate can irritate the nose, throat and lungs causing coughing. Chronic Health Effects The following chronic (longterm) health effects can occur at ... Use dry chemical, CO 2, water spray or as extinguishing agents.
Calcium carbide can be stored outdoors in unopened sealed metal containers. Grounding of calcium carbide containers while in use is recommended to prevent static electricity discharge. Frequent periodic examination of containers should be made to check for excessive Illsting. Do not attempt to repair any calcium carbide container. Elkem
