calcium carbide conditions

  • Calcium Carbide | AMERICAN ELEMENTS

    Calcium Carbide is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered. Carbides are compounds in which the anion is one or more carbon atoms. Most metals form carbide compounds, though not all: Indium and Gallium, for example, do not.

    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].

  • Calcium Carbide Moisture Test - The Screed Scientist®

    Calcium Carbide Moisture Test. Overview. The calcium carbide method is one of the most accurate and reliable methods of moisture testing, as the results do not just indicate the moisture levels for the surface of the screed, but it also provides an accurate measurement of the moisture present in the screed to a depth of up to 50% of its thickness.

  • Calcium carbide (CaC2) reacts with water to form acetylene ...

    Oct 15, 2007 · Best Answer: Convert all quantities in moles. Divide 3.50kg by the molecular weight of CaC2 (gives 54.68 mol). The density of water (supposing STP conditions) is 1 so 1L=1kg. Divide that by water's molecular weight (gives 55,5 mol). 1 mole of CaC2 reacts with 2 moles of water.You have to find which one (water or CaC2) is abundant: 54.68 mol CaC2 needs 2*55,5 mol.
