Strontium sulfate is an inorganic compound with the chemical formula SRSO4, it is a white crystalline powder that is soluble in water and insoluble in ethanol. Strontium sulfate is hygroscopic and becomes moist when exposed to air by absorbing moisture. It is commonly used as a white pigment, ceramic glaze, fluorescent material, etc.
The crystal structure of strontium sulfate is a cubic crystal system, the space group is p213, and each unit cell contains 4 srSO4 molecules. In strontium sulfate crystals, the ionic bond between SR2+ and SO42- is strong, forming a stable crystal structure. In addition, strontium sulfate crystals also have a high refractive index and low electrical conductivity, which make them have a wide range of applications in the fields of optics, electronics, and ceramics.
There are several production methods for strontium sulfate, one of which is to use the reaction of sulfuric acid and strontium oxide to produce strontium sulfate. Another method is to use the reaction of strontium hydroxide and sulfuric acid to produce strontium sulfate and water. These methods require attention to reaction conditions and purity control to ensure the generation of high-quality strontium sulfate products.
Strontium sulfate is not absorbed in the human body and is therefore considered a safe food additive. Adding an appropriate amount of strontium sulfate to food can increase the taste of food, improve the texture of food, and improve the nutritional value of food. However, it is important to note that excessive intake of strontium sulfate may cause uncomfortable symptoms such as diarrhea.
