Mixing calcium carbide with silver nitrate solutions forms silver acetylide, a highly sensitive explosive. Copper salt solutions would behave similarly, [Photogr. Sci. Eng., 1966, 10, 334]. The mixture of calcium carbide and sodium peroxide is explosive, as is calcium carbide and perchloryl fluoride as gases at 100-300°C.

The temperatures involved in the production of calcium carbide mean that only professionals trained in the use of the required equipment should attempt to make calcium carbide. Crush the solid calcium carbide in either an open-air setting or inert environment prior to it cooling completely. Failure to do so can lead to an explosion hazard.
Calcium carbide brings a new green and sustainable wave into powerful alkyne transformations and significantly expands the repertoire of traditional acetylene chemistry. The novel trend of using calcium carbide instead of gaseous acetylene is synthetically beneficial and opens a novel reactivity for the C≡C unit. This review highlights recent ...

Consequently, increased pressure has been placed on the foundry industry to reduce the reactivity of this slag.To address this problem, Cyanamid has developed a new product which significantly reduces the calcium carbide content of the …
1. Physical Properties of Calcium Carbide. Calcium carbide, CaC 2, is a binary ionic compound with a molar mass of 64.10 g/mol.In its pure form, it is colorless and odorless. However, technical-grade material often exhibits various shades of grey to brownish black, occasionally with violet or red-brown hues, due to impurities.
Calcium Carbide in its pure form is colouress but its technical grade pieces are grey or brown in colour. They consist of approximately 80-8596 Calcium Carbide, the rest is calcium oxide,calcium phosphide, calcium sulfde, and calcium nitride etc.Calcium Carbide emits an unpleasant garic ike odour in the presence of moistur
