Calcium Carbide Market Size, Share, Opportunities, And Trends By Application (Acetylene Gas, Calcium Cyanamide, Reducing and Dehydrating Agent, Desulfurizing and Deoxidizing Agent, Others), By End-Use Industry (Chemical, Metalluary, Others), And By Geography - Forecasts From 2025 To 2030

The calcium carbide market is estimated at US$18.314 billion in 2025 and is anticipated to grow at a CAGR of 3.19% during the forecast period and reach US$21.431 billion in 2030.

Calcium carbide is a grayish-black solid compound of chemistry that reacts with water to give acetylene gas (C?H?) and calcium hydroxide. The most widespread use of calcium carbide these days is in the industrial production of acetylene, a major fuel in welding and metal cutting, and as a precursor in the chemical synthesis of organic compounds in general. Other uses of calcium carbide are in the manufacture of calcium cyanamide important source of nitrogen fertilizer in the desulfurization of iron.

In addition, the demand for calcium carbide is anticipated to grow, owing to the increase in the steel sector.

The increasing investment in the construction and automotive sectors is fuelling the demand for steel, which is propelling the calcium carbide market growth. For instance, according to the National Bureau of Statistics of China, the total value added to the industrial sector in 2023 was 39,910.3 billion yuan, which was 4.2% higher than in 2022. Similarly, the value added of construction enterprises was 8,569.1 billion yuan in 2023, which was 7.2% higher compared to 2022.

Similarly, according to the U.S. Department of Commerce, the total construction spending in the United States in July 2024 was US$2,162.7 billion, which was 6.7% higher than that of 2023, where the construction spending was US$2,027.4 billion. Hence, with the growing application of calcium carbide in various end-use sectors, the market for calcium carbide is expected to grow substantially in the projected period.

What are the calcium carbide market drivers?

• The growing demand for acetylene and acetylene derivatives is expected to impact the market for calcium carbide in the forecasted period. Acetylene is used in producing various chemicals, and its derivatives are used in producing resin, fiber, and polymer, among others. Furthermore, the use of acetylene in the rubber, dye, pharmaceutical, and plastic sectors is expected to impact the calcium carbide market in the projected period.
• The growing plastic sector is anticipated to boost the demand for calcium carbide in the coming years. For instance, according to the Indian Brand Equity Foundation (IBEF), there are currently 50,000 plastic-producing industries in the country, most of which are micro, small, and medium enterprises (MSMEs). Moreover, these plastic industries in India are expected to contribute INR3.5 lakh crore (or USD42.89 billion) to the Indian economy.   
• Furthermore, calcium carbide is mainly used for desulfurization purposes in steel production; it removes sulfur impurities from molten iron, otherwise making the steel brittle and weakening its structural properties. Hence, calcium carbide plays a major role in the production of steel, which helps in reducing sulfur content and producing high-quality steel. When calcium carbide is added to molten steel, it reacts with sulfur to form calcium sulfide, which can easily be removed, thereby helping improve its strength, durability, and quality.
• For instance, according to the Ministry of Steel, India, both the production and consumption of steel are increasing rapidly in the country; the per capita steel consumption in India increased from 59kg in 2013-14 to 119kg in 2022-23. Additionally, the production of steel in India in 2023 was 140.2 million tonnes, positioning the country second in global steel production. Additionally, the National Steel Policy (NSP) projects are anticipated to impact the country's steel market. By 2030-31, India aims to achieve a total crude steel capacity of 300 million tonnes, with crude production reaching 255 million tonnes and final steel production to 230 million tonnes. Hence, the increasing production of steel is anticipated to positively influence the calcium carbide market in the projected period.

Segment analysis of the calcium carbide market:

• By application, the acetylene gas segment is expected to hold a significant share of the calcium carbide market.

By application, the calcium carbide market is segmented into acetylene gas, calcium cyanamide, reducing & dehydrating agents, steelmaking, and others. The acetylene gas segment is anticipated to hold a significant market share in the projected period, owing to increasing demand for acetylene gas in various applications such as oxyacetylene welding, dyestuff industries, and manufacturing plastics and synthetic rubber. The increasing use of acetylene gas for producing polyvinyl chloride, preferred in producing wires, cables, films, and sheets, is expected to increase the demand for the acetylene segment in the forecasted period.

• By end-user segment, the chemical industry is anticipated to hold a significant share of the calcium carbide market.

The chemical sector is expected to hold a significant market share in the calcium carbide market, as calcium carbide is used for synthesis chemicals, including calcium cyanimide and other organic chemicals. Additionally, the use of calcium carbide for the production of acetylene and acetylene derivates, which are being majorly used in the pharmaceutical and plastic industries, is anticipated to boost the market for calcium carbide.

Geographical outlooks of the calcium carbide market:

• The Asia Pacific region is anticipated to hold a significant share in the coming years.

The Asia Pacific region is expected to grow at a noteworthy rate due to the propelling steel and chemical manufacturing industry in countries such as India and China. China is one of the major producers of crude steel. According to the World Steel Association, crude steel production in China was 90.2 million tons in May 2023 and grew to 92.6 million tons in May 2024. Additionally, the rising production of PVC in the region is expected to positively influence the market for calcium carbide in the forecasted period. Similarly, the North American region is anticipated to grow in the coming year due to increased demand for chemicals and steel in various end-use industrial sectors.

Key developments in the calcium carbide market:

• In May 2024, DCT Chemicals, a leading provider of caustic soda, chlorine, calcium carbide, aluminum chloride, PVC resins, and PVC compounds, among others, signed a Memorandum of Understanding (MoU) with the Institute of Chemical Technology (ICT), Mumbai. This collaboration aims to advance the research and development of the chemical industry, leveraging ICT's academic prowess and DCM Shriram's industrial expertise.
