Calcium oxide has huge demand and the market size is expected to continue to grow

Calcium oxide, commonly known as quicklime, has a chemical formula of CaO. The surface of calcium oxide is white powder, if it is impure, it is off-white, and if it contains impurities, it will be gray or light yellow. Calcium oxide has stable chemical properties and is hygroscopic. When exposed to the air, it will react with water in the air to generate calcium hydroxide with the chemical formula Ca(OH)₂, which is also accompanied by the generation of heat. , calcium hydroxide dissolves in water and becomes alkaline. Lime also reacts chemically with carbon dioxide (CO₂) in the air to produce white solid calcium carbonate (chemical formula CaCO₃) that is insoluble in water. Calcium oxide is soluble in acid water, soluble in some vegetable oils and sugars, such as glycerin and sucrose, etc., and is difficult to tolerate in ethanol. Its relative density is between 3.32-3.35, boiling point is 2850°C, melting point is 2572°C, and refractive index is 1.838. It is an inorganic alkaline corrosive product, national dangerous regulations number 95006.

Calcium oxide can be used as analytical reagents, spectral analysis reagents, co-solvents for phosphors, vegetable oil decolorizers, carbon dioxide absorbers, building materials, refractory materials, desiccants, soil conditioners and calcium fertilizers, etc. It is widely used in the chemical industry, metallurgy Industry, construction industry, agriculture and environmental protection industry and other fields. In recent years, affected by the development of downstream industries, the demand market for calcium oxide industry has a stable growth trend.

At present, the key manufacturers in the global calcium oxide industry are mainly European and American companies, including Germany’s Lhoist Group, Switzerland’s Maerz Ofenbau, Germany’s Kalkwerke Oetelsofen, Yoshizawa Lime Industry Co., Ltd., etc. The above-mentioned companies occupy the main share of the global high-end calcium oxide market and dominate the market. Standards and technical trends of calcium oxide products. my country’s calcium oxide industry has a large number of enterprises in the calcium oxide industry, but there are many small and medium-sized enterprises in the industry and the production capacity is scattered. Key enterprises include Sichuan Jinding (Group) Co., Ltd., Hunan Haocheng Technology Co., Ltd., and Zhejiang Tianshi Nanotechnology Co., Ltd. Co., Ltd., Xuzhou Weihua Furnace Charge Co., Ltd., etc., due to their short R&D and industrialization time, are at a disadvantage in the competition in the global calcium oxide industry. According to the “China Calcium Oxide Market Analysis and Development Prospects Research Report 2021-2025” released by the Industrial Research Center, in recent years, my country’s calcium oxide output continues to grow, and its market size is also expanding. In 2022, China’s calcium oxide market size will be 150 billion yuan.

Industrial Analysts People said that the calcium oxide industry is a subdivision of my country’s basic chemical industry and plays an important role in my country’s chemical industry. important economic support role. The upstream of calcium oxide is the raw material industry such as limestone, and the downstream is the building materials, metallurgy, chemical industry, environmental protection, agriculture, food and other industries. The production technology threshold of the calcium oxide industry is low, so there are many calcium oxide production companies in my country, but most of them are small in scale and have imperfect product structures. Industrial-grade products with low content and large particle size are the mainstream products in the calcium oxide market. . With the continuous development of the calcium oxide downstream industry, the demand for fine calcium oxide and high-grade calcium oxide products is gradually increasing, prompting my country’s calcium oxide production enterprises to continue to develop in the direction of high quality and high-end. Overall, the development of my country’s calcium oxide industry is still immature, the production capacity of high-end products needs to be improved, and the product structure also needs to be adjusted and optimized. In the future, as the influence of national macroeconomic regulation and environmental governance increases, the market space of the calcium oxide industry will further expand.
