Desulfurization gypsum powder, natural gypsum powder and phosphogypsum powder are the most used gypsum powder raw materials in gypsum powder production line. They are usually composed of sulfur trioxides, alumina, iron trioxides, calcium oxide, magnesium oxide and potassium oxide.

　　其中，脱硫石膏粉还含有二氧化硅、氧化钠、碳酸钙、亚硫酸盐、石灰石、氯化钙、氯化镁等。与其他石膏粉相比，脱硫石膏粉具有再生、粒度小、组成稳定、有害杂质少、纯度高等特点。

　　Among them, desulfurization gypsum powder also contains silica, sodium oxide, calcium carbonate, sulfite, limestone, calcium chloride, magnesium chloride, etc. Compared with other gypsum powder, FGD gypsum powder has the characteristics of regeneration, small particle size, stable composition, less harmful impurities and high purity.

　　在构成石膏粉的基本化学成分中，脱硫石膏含量高的是三氧化硫，约占45%，其次是氧化钙、二氧化硅、氧化镁、氧化铝、三氧化铁、氧化钾和氧化钠。

　　In the basic chemical composition of gypsum powder, the highest content of desulfurized gypsum is sulfur trioxide, accounting for about 45%, followed by calcium oxide, silicon dioxide, magnesium oxide, aluminum oxide, iron trioxide, potassium oxide and sodium oxide.

　　天然石膏粉中氧化钾的含量多，约占44%，其次是氧化钙、三氧化硫、氧化铝和三氧化铁的含量相同。天然石膏粉不含二氧化硅、氧化镁或氧化钠。

　　The content of potassium oxide in natural gypsum powder is the most, accounting for 44%, followed by calcium oxide, sulfur trioxide, alumina and iron trioxide. Natural gypsum powder does not contain silica, magnesium oxide or sodium oxide.

　　磷石膏粉和脱硫石膏粉，也是三氧化二硫含量多的，约占41%，其次是氧化钙、氧化镁、氧化铝、氧化铁含量由多到少。磷石膏粉不含二氧化硅、氧化钠或氧化钾。

　　Phosphogypsum powder and desulfurized gypsum powder also have the most sulfur dioxide content, accounting for about 41%, followed by calcium oxide, magnesium oxide, alumina and iron oxide. Phosphogypsum powder does not contain silica, sodium oxide or potassium oxide.
