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.
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 ...
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.
2) heating the powdered calcium carbide and nitrogen, the reaction to produce calcium cyanide, that is, lime nitrogen, heated lime nitrogen and salt reaction generated by the cyanide melt for the gold and nonferrous metals industry. 3) Calcium carbide itself can be used in the iron and steel industry desulfurization agent.
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.
Calcium carbide, when coming across with water or steam, generates acetylene and release a large amount of heating. CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 + 125185.32J, 1kg of pure calcium carbide can produce 366 L of acetylene 366l (15 ℃, 0.1MPa). Thereby, for its storage: calcium carbide should be strictly kept away from water.
Bulk Calcium Carbide cac2, US $ 300 - 620 / Ton, Other Inorganic Salts, 7778-50-9, CaC2.Source from Shouguang Hengyi Chemical Technology Co., Ltd. on Alibaba.
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 .

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 .
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 carbon-containing calcium carbonate and from about 1% to 12% of high volatile, bituminous coal dust.
Jul 19, 2018· The best way to kill wasps, in this case, is to use a spray of aerosol. It will kill the angry wasps quickly. You can also use a wasp killer dust or powder to kill the yellow jackets. It is better not to use a puffer duster as it can turn out to be risky. Get a bellow duster and coat the outsides of the wasp nest with the powder.
1. Integrated Steelmakers: (Low Cost, Powerful Desulfurizing) Calcium carbide is a powerful and effective chemical reducing agent. Nowhere is this more evident than in the field of metallurgy, where it is added to liquid iron and steel through subsurface pneumatic powder injection in order to remove sulfur impurities prior to the final steelmaking process.
Calcium oxide is then heated in electric furnace with coke to produce calcium carbide finally calcium carbide is hydrolyzed producing acetylene. As acetylene is colorless gas and is highly combustible with high flame speed and fast energy release, it can be used as alternative fuel in IC engines.
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 .
Flue Gas Desulfurization And Dust Removal Device Bag filter is suitable for refractory processing dust removal, steel making electric furnace flue gas dust removal, abrasive processing workshop dust removal, calcium carbide furnace production dust removal, blast furnace gas purification, pulverized coal preparation dust removal, asphalt concrete production dust removal, carbon black production ...
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-
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.
