Published March 2017. Calcium carbide is an inorganic compound with the following primary commercial applications: generation of acetylene, production of calcium cyanamide (a nitrogen fertilizer), and use in the iron (foundry) and steel industries as a desulfurization reagent in the production of ductile iron and steel and as a slag modifier/conditioner (reducer) in steel production.
The oldest method of preparing acetylene is the treatment of calcium carbide with water at room temperature (2), by which acetylene and calcium hydroxide are formed. Calcium carbide is produced by heating coke with calcium oxide (limestone) in an electrical furnace up to 2000 °C (1), which results in the desired product and carbon monoxide (CO).

The method involves the production of calcium carbide enriched in oxygen and carbon monoxide CO in a high-temperature melting furnace, where limestone and carbonaceous materials react like coal. Further acetylene and dichloroethane are produced from calcium carbide and CO (with ethylene, etc. through methanol or ethanol).

Resisting wear is one of the greatest challenges for moving components. To help fight high- and low-temperature wear, we offer a complete line of spray dried, cast and sintered carbide powder solutions. See our APT, chromium carbide and tungsten carbide powder formulas below.
Calcium carbide is also an intermediate product in the smelting of calcium–silicon alloy. Technical grade calcium carbide is crystallized from the melt and contains ~80% CaC 2 and 10% to 15% CaO (Fig. 19.4). Commercial calcium carbide is a gray-black material due to the presence of residual carbon.

At Carbide Industries, calcium carbide production in different sizes (grades) is all we do. Generally speaking, the different grades of carbide that we make correspond to different reactivities of the carbide. For example, we produce fast-acting carbide powder that is injected into molten iron to combine with and remove sulfur.

Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C 2.Its main use industrially is in the production of acetylene and calcium cyanamide.. The pure material is colorless, however pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of CaC 2 (the rest is CaO (calcium oxide), Ca 3 P 2 (calcium phosphide ...

Nov 06, 2015· Abstract: Calcium carbide (CaC 2) is known for its wide applications in the production of acetylene and calcium cyanamide, whereas praseodymium Oxide (Pr 6 O 11) is used in sensors and high-temperature pigments.The present study was designed to evaluate the effect of biofield energy treatment on the physical and structural properties of CaC 2 and Pr 6 O 11 powder.
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders. PM processes can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs.
The ultrafine powder production and processing is crucial. At present, the method for the production of ultra-fine powders is mainly two ways: First, the physical methods. Second, chemical synthesis, there is the method on the basis of these two mixed. Nanomaterials generally take a mixed legal system.
Production of calcium carbide in China has been increasing. In 2005 output was 8.94 million tons, with the capacity to produce 17 million tons. In the United States, Europe, and Japan, consumption of calcium carbide is generally declining. Production levels in .
By the late 1800s, a method had been developed for making acetylene by reacting calcium carbide with water. This generated a controlled flow of acetylene that could be combusted in air to produce a brilliant white light.
