Sodium carbonate (Na2CO3), molecular weight 105.99. More than the purity of chemicals in more than 99.5% (mass fraction), also known as soda ash, but the classification is a salt, not a base. Also known as soda or soda ash in international trade. It is an important organic chemical raw material, mainly used in the production of flat glass, glass products and ceramic glaze. Also widely used in life washing, acid and food processing.

Basic chemical raw materials, widely used in medicine (medical treatment for hyperacidity), paper, metallurgy, glass, textiles, dyes and other industries, as the food industry fermentation agent

During the "11th Five-Year Plan" period, the soda ash production capacity in our country developed rapidly. With the release of new production capacity and intensified competition, the market price fluctuated cyclically and the economic benefits of soda ash industry dropped sharply. The unexpected financial crisis intensified in the second half of 2008. Soda industry adverse situation, leading to sharp fluctuations in soda ash prices. Affected by the financial crisis, downstream demand downturn in 2009, soda ash prices fell to the bottom, resulting in loss-making industry. The domestic economy stabilized and rebounded in 2010, with the market demand increasing. Soda ash output then rose rapidly. The investment enthusiasm of domestic enterprises began to rise gradually. It is estimated that there will be a large number of new capacity releases during the "12th Five-Year Plan" period, and the soda ash industry is likely to once again Into the downlink cycle.

[1] Mostly from the development of small and medium nitrogen fertilizer companies, enterprises in the international comprehensive competitiveness is poor. In recent years, China's soda ash production capacity has grown rapidly, overcapacity serious, and "Twelve Five" period, there will be more than 6 million tons of new capacity into the market, which will further aggravate the situation of excess capacity of soda ash in our country, The competition of enterprises will also be further aggravated. Merger and reorganization within the industry and between upstream and downstream will make new progress.
