Manufacturing Refractory Ammonium Sulfate: A Complete Guide
Refractory ammonium sulfate is an essential ingredient in the manufacture of refractory bricks and castables used in high temperature applications. This article introduces the production process and applications of refractory ammonium sulfate.
What is Manufacturing refractory Ammonium Sulfate?
Refractory ammonium sulfate is an inorganic compound used as a binder in the manufacture of refractory bricks and castables. It is a white crystalline solid, soluble in water, with a melting point of 235°C.
Application of refractory ammonium sulfate
Manufacturing refractory Ammonium Sulfate is commonly used in the manufacture of refractory bricks and castables, and is widely used in high-temperature applications such as furnaces, kilns, and incinerators. Refractory bricks made with ammonium sulfate have high thermal shock resistance, high compressive strength and excellent wear resistance.
Additionally, ammonium sulfate is used as a fertilizer in agriculture. It is a good source of nitrogen and sulfur, essential nutrients for plant growth.
in conclusion
Manufacturing refractory Ammonium Sulfate is an important raw material for the production of high-temperature refractory bricks and castables. The production process includes the production of sulfuric acid, neutralization and crystallization. The final product is a white crystalline solid that is soluble in water and has a melting point of 235°C. In addition to its use in the refractory industry, ammonium sulfate is also used as a fertilizer in the agricultural industry.
