China's mirabilite mineral resources are very rich to reach the first of world. In recent years, with the development of industry, sodium sulfide, as one of the products of Glauber’s salt, has been fully used in various fields. While sodium sulfide industry has a bright future, have you ever thought of who discover sodium sulfide first?

History Of Sodium Sulfide
Unlike barium sulfate, there is no natural sodium sulfide in nature. The production of this martials dates back at least 350. As early as the middle ages, alchemists made potassium sulfide by heating sulfur and potassium carbonate.
By 1658, the Dutch Glauber used sodium sulfate with charcoal heat producing sodium sulfide, from then on, the whole world's production of sodium sulfide is produced by reducing thernadite with coke. Until the 1950s, the product produced by other methods was very limited, and most of the materials products were produced by reducing thernadite with coal or coke.
Development Of Chinese Sodium Sulfide
1. 1830s
China's sodium sulfide originated in the 1830s and was first produced on a small scale by a chemical plant in Dalian, Liaoning province. The quality standard at that time was (Na2S 42%).
2. In the early 1940s
the production of solid sodium sulfide was also started in Tianjin chemical plant, and the quality standard was improved to 52% (Na2S).
3. By the mid-1950s
The output of which in Shanxi Yuncheng had reached more than 10,000 tons. The quality standard is based on the former Soviet Union (Na2S 63%).
4. By the end of 1970s
The output of sodium sulfide in Yuncheng had further increased, and its production capacity had reached 70,000-80,000 tons. The quality standard is in accordance with the national standard of the People's Republic of China gb10500-89 (Na2S 60%).
5. In the 1980s to the mid-1990s
With the rapid development of the international chemical industry, China's industry has undergone a fundamental transformation, and the sodium sulfide manufacturers and scale have increased dramatically and developed rapidly. The national mineral production capacity soared from 420,000 tons in the late 1980s to 640,000 tons in the mid-1990s. The production capacity of which in Inner Mongolia has reached 200,000 tons, making it the largest production base of sodium sulfide products in China.
As a result, after more than 70 years of hard work, China's sodium sulfide industry has not only made brilliant achievements, but also ranked among the world's advanced ranks. Its total output has occupied the world 21 sodium sulfide producer country to lead. China has become the world's largest producer of various sodium sulfide products.
Significance Of Investment In Sodium Sulfide
With the development of industrialization in China, building a resource-saving and environment-friendly society is the inevitable requirement of economic development for industrialization. Energy conservation and emission reduction work has a long way to go, which can effectively alleviate the contradiction between economic development and resources and environment. Coal reduction mirabilite process is mostly used in the production of sodium sulfide in China. This process has low resource utilization, high energy consumption, high production cost and poor economic benefit. Accelerate the transformation and upgrading of sodium sulfide production process and production equipment, effectively achieve energy saving and emission reduction, social and economic benefits are obvious.
While we are not the ones discovering sodium sulfide, we can become the ones who contributes to the development of this industry. The investment to these new materials is of great importance you have interested in cooperating with our company Shaanxi Fuhua Chemical Co., Ltd., welcome to contact us at any time.
