Pure CaC2, free of CaO impurities, was obtained by the reaction of elemental calcium with graphite at 1,070 K. By means of laboratory X-ray and synchrotron powder diffraction experiments, the phase diagram was investigated in the temperature range from 10 K to 823 K; this confirmed the literature da …
Various sources of carbon can be converted into acetylene (C2H2) by using the key intermediate calcium carbide (CaC2). However, the production of CaC2 is a typical energy …

The traditional calcium carbide (CaC2) production process (TCCPP) uses block CaC2 and coke as the main raw materials and produces CaC2 through electrothermal smelting in an arc furnace.
At the initial stage of the reaction, a solid layer of CaC2 starts to form at the interface of C and CaO above 1460 °C. The as-formed CaC2 layer prevents the diffusion of CaO into C. …
Calcium carbide is an inorganic compound with the chemical formula CaC2. It is a colorless, odorless, and flammable gas. It is a useful material in the production of acetylene gas.
CaC2 production with pulverized feeds was proven viable at temperatures about 400 °C lower than that required by the current electric arc technology (2100–2200 °C), which led to development of an a...
Calcium Carbide (CaC2) - Calcium Carbide is a colorless and odorless solid. Calcium Carbide is the chemical name of CaC2. For an in-depth knowledge on the uses, …
Development of calcium coke for CaC2 production using calcium carbide slag and coking coal
At the initial stage of the reaction, a solid layer of CaC2 starts to form at the interface of C and CaO above 1460 °C. The as-formed CaC2 layer prevents the diffusion of CaO into C. However, above 1660 °C, CaC2 and CaO forms a eutectic mixture which further promotes the diffusion of CaO and formation of CaC2.
It is argued that a complete understanding of the occurrence of three room temperature modifications of CaC2 will require a detailed characterization of compositional and structural …
Various sources of carbon can be converted into acetylene (C2H2) by using the key intermediate calcium carbide (CaC2). However, the production of CaC2 is a typical energy-intensive process, accompanied by considerable carbon dioxide (CO2) emissions and a large amount of industrial solid waste.
Calcium Carbide (CaC2) - Calcium Carbide is a colorless and odorless solid. Calcium Carbide is the chemical name of CaC2. For an in-depth knowledge on the uses, physical and chemical properties, structure of Calcium Carbide (CaC2) visit BYJU'S.
It is argued that a complete understanding of the occurrence of three room temperature modifications of CaC2 will require a detailed characterization of compositional and structural heterogeneities within the high temperature form CaC2-IV, which is stable above 450 °C.
CaC2 production with pulverized feeds was proven viable at temperatures about 400 °C lower than that required by the current electric arc technology (2100–2200 °C), which …
Calcium carbide, CaC 2, is one of the most recognized inorganic compounds.In textbooks it is often introduced as the prototype for salt-like carbides. CaC 2 is a so-called acetylide, featuring C 2 2− dumbbell anions isoelectronic to dinitrogen [1], [2], [3].The simple …
