Buy wholesale calcium carbide in Ukraine
Calcium carbide has a hard crystalline structure. In its pure form, the substance consists of white crystals. Pieces of technical carbonaceous calcium can have a dark gray, brown or black color. The shade acquired by the substance is due to the fact that the production of calcium carbide is carried out in electric furnaces by fusing quicklime and coal at a high temperature, reaching 1900-1950°C.
The chemical formula is CaC 2 .

Warranty and storage
The company "Khimsnabzhenie" guarantees the quality and originality of chemical products.
Calcium carbide is packed in steel drums or airtight containers. Upon contact with water, calcium acetylenide decomposes, in which calcium hydroxide and acetylene are released. Interaction with oxidizing agents also leads to the release of acetylene and heating of the product. This substance is assigned to the 1st hazard class in terms of effects on the human body, so its storage and use requires strict adherence to safety rules. You can store calcium carbide for 6 months from the date of manufacture.
Calcium carbide can be stored in open areas equipped with a canopy or well-ventilated warehouses built of non-combustible materials and protected from moisture. Drums should be stacked vertically, not more than three tiers in height, and proximity to other materials should not be allowed.
