Carbide

Examples

• The cheapness of calcium carbide has made it possible for the isolated farmhouse to discard oil lamps and to have a private gas system. Bertha M. Clark. General Science.
• The oven filled with calcium carbide is then electrically heated with a carbon rod running through the center. Various. The Wonder Book of Knowledge.
• In a house in which there were twenty burners, the tanks were filled with water and carbide but once a fortnight. Bertha M. Clark. General Science.
• When chemical action between the water and carbide has ceased, and gas bubbles have stopped forming, slaked lime is all that is left of the dark gray crystals which were put into the water. Bertha M. Clark. General Science.
• When the temperature is about as hot as that of molten iron the pure nitrogen gas from the liquid air plant is pumped in and allowed to act on the calcium carbide for about a day and a half. Various. The Wonder Book of Knowledge.
• When the hard, gray crystals of calcium carbide are put in water, they give off acetylene, a colorless gas which burns with a brilliant white flame. Bertha M. Clark. General Science.
• When nitrogen gas is in contact with heated calcium carbide, a reaction takes place which results in the formation of calcium nitride, a compound suitable for enriching the soil. Bertha M. Clark. General Science.
• At the cyanamid plant at Niagara Falls, in Canada, there are seven of these great carbide furnaces, each about fifteen feet long and half as wide and one-third as deep. Various. The Wonder Book of Knowledge.
• In 1892 it was discovered that lime and coal fused together in the intense heat of the electric furnace formed a crystalline, metallic-looking substance called calcium carbide. Bertha M. Clark. General Science.
• A number of receptacles containing charges of calcium carbide are made to successively receive a regulated quantity of water, the gas being collected in a rising and falling holder. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• Acetylene Gas from Calcium Carbide by Willson. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• In acetylene gas apparatus a great variety of methods are employed for bringing the water and carbide into contact. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• In the carbide furnace the carbon pencil, instead of being six or eight inches long and as large around as your finger, is six feet long and two feet in diameter. Various. The Wonder Book of Knowledge.
• It is now made commercially by the mutual decomposition of water and calcium carbide, the latter giving off, when brought in contact with the water, acetylene gas, which rises in bubbles. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
• When so drawn off, the pressure in the inner cylinder is relieved, and the water therein rises to contact again with the calcium carbide and renews the generation of gas. Edward W. Byrn. The Progress of Invention in the Nineteenth Century.
