Описание: In this video, we explore apatite, a group of phosphate minerals with a chemical composition of calcium phosphate (Ca5(PO4)3(F,Cl,OH)). Apatite comes in various colors, including green, blue, yellow, and purple, with a hardness of 5 on the Mohs scale. It forms hexagonal crystals and has a specific gravity of 3.1 to 3.2, making it relatively lightweight. With a vitreous luster and a white streak, apatite is found in igneous, sedimentary, and metamorphic rocks, with deposits in Brazil, Russia, Canada, and Mexico. It’s vital for both biological and industrial uses, particularly in the production of fertilizers.
