  • Calcium Carbide an overview ScienceDirect Topics

    Calcium carbide has the nominal formula of CaC 2 and the molecular weight of 64.0992 g/mol. The pure material is colorless, but most samples have a color ranging from black to grayish-white, depending on the grade. Its density is 2.22 g/cc and it melts at 2160 °C with a boiling point (under an inert atmosphere) of 2300 °C, where it decomposes.Its main use industrially is in the production of

  • Preparation of Calcium Carbonate Superfine Powder

    2012-1-1 · Abstract. Calcium carbonate superfine powder with high purity was prepared from calcium carbide residue by a liquid phase process using ammonium chloride as extraction agent and ammonium carbonate agent. The effects of some factors on the reaction were investigated. The calcium carbonate was characterized by X-ray powder diffraction device (XRD
