What is the Calcium Carbide?

Calcium Carbide is also called calcium acetylide, which is a chemical compound having the chemical formula of CaC2. Mainly, it is used industrially for the production of calcium cyanimide and acetylene and Ethylene. The material in its pure form is without color however the industrial calcium carbide compounds are either brown or grey and consist of about 80–85% of CaC2 (the remaining is CaO – calcium oxide, Ca3P2 – calcium phosphide, Ca3N2 – calcium nitride, CaS – calcium sulfide, SiC – silicon carbide and more). In trace moisture presence, the carbide technical-grade emits an unpleasant odor which is reminiscent of garlic and also the material explodes in presence of certain amount of water.

CAS Number for Calcium Carbide is 75-20-7 and it has the EC number of 200-848-3

The high temperature that is required for this reaction is practically not achievable by traditional combustion. So, this reaction is performed in an electric arc furnace using graphite electrodes. By weight, the produced carbide product will contain around 80% of the calcium carbide. Also, carbide is further crushed to produce small lumps that can range up to a maximum of 50 mm, and the impurities are concentrated in the finer fractions.

As a leading calcium carbide supplier, NEW OCEAN GROUP recognizes the significance of calcium carbide's emergence in solving challenges in these sectors.

The main component of carbide slag slurry is calcium hydroxide (Ca (OH) 2). Calcium carbide slag slurry is a gray brown turbid liquid.

High purity calcium carbide is a chemical compound, primarily composed of calcium and carbon (CaC₂), that boasts remarkable purity levels exceeding 98%. Its primary application in industrial settings revolves around its use in producing acetylene gas, which serves as a fundamental building block in various chemical processes.

Calcium carbide plays a significant role in various industries, particularly in chemical manufacturing and agricultural practices. As a key chemical compound, its emergence has transformed processes by enhancing efficiency and productivity.

Finding quality calcium carbide can be challenging, especially for overseas buyers and distributors. Many companies struggle with searching for reliable suppliers, ensuring product quality, and understanding import regulations. Calcium carbide is used in various applications, including steelmaking, producing acetylene gas, and manufacturing PVC.

Polyvinyl chloride (PVC) is one of the most widely used synthetic plastic polymers, commonly produced through two main methods: the calcium carbide method and the ethylene method. This article provides an in-depth comparative analysis of both approaches, focusing on their advantages, disadvantages, and suitable applications.
