Fluorgypsum yog ib qho pov tseg ntawm calcium sulfate. Nws tsim los ntawm cov tshuaj tiv thaiv fo sulfuric acid thiab fluorite hauv kev tsim cov hydrofluoric acid. Nws yog tsuas yog los ntawm cov tuam txhab fluoride, suav nrog inorganic fluoride thiab organic fluoride ntau lawm cov nroj tsuag thiab lwm yam hydrofluoric acid ntau lawm cov nroj tsuag.
Fluorite thiab sulfuric acid sib tov ntawm qhov sib piv ntawm 1: 1.3 thiab rhuab nyob rau hauv lub cub tawg teb (250-280 degrees). Tom qab cov tshuaj tiv thaiv tshuaj: CaF2 ntxiv rau H2SO4=CaSO4 ntxiv rau 2HF, nws yuav tsimHydrogen fluoride (HF) thiab calcium sulfate (CaSO4).Hydrogen fluoride gas yog condensed thiab sau los tsim hydrofluoric acid, thiab cov khoom siv: calcium sulfate yog gypsum.Vim tias nws muaj me me ntawm CaF2 uas tsis muaj kev cuam tshuam, nws tseem hu ua fluorogypsum.
