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，脫硫石膏粉還含有二氧化硅、氧化鈉、碳酸鈣、亞硫酸鹽、石灰石、氯化鈣、氯化鎂等。與其他石膏粉相比，脫硫石膏粉具有再生、粒度小、組成穩定、有害雜質少、純度高等特點。

　　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.

　　在構成石膏粉的基本化學成分中，脫硫石膏含量高的是三氧化硫，約占45%，其次是氧化鈣、二氧化硅、氧化鎂、氧化鋁、三氧化鐵、氧化鉀和氧化鈉。

　　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.

　　天然石膏粉中氧化鉀的含量多，約占44%，其次是氧化鈣、三氧化硫、氧化鋁和三氧化鐵的含量相同。天然石膏粉不含二氧化硅、氧化鎂或氧化鈉。

　　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.

　　磷石膏粉和脫硫石膏粉，也是三氧化二硫含量多的，約占41%，其次是氧化鈣、氧化鎂、氧化鋁、氧化鐵含量由多到少。磷石膏粉不含二氧化硅、氧化鈉或氧化鉀。

　　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.
