Sau uku superphosphate a cikin takin Phosphate
Sau uku superphosphate (TSP), An yi shi ta hanyar maida hankali phosphoric acid da ƙasa phosphate dutse. Yana da babban taro ruwa mai narkewa taki phosphate, kuma yadu amfani ga da yawa ƙasa. Ana iya amfani da shi don zama taki na asali, ƙarin taki, takin ƙwayar cuta da albarkatun ƙasa don samar da takin zamani.
TSP babban taro ne, taki phosphate mai narkewa da sauri, kuma ingantaccen abun cikinsa na phosphorus shine sau 2.5 zuwa 3.0 fiye da na calcium na yau da kullun (SSP). Ana iya amfani da samfurin azaman taki mai tushe, suturar sama, takin iri da albarkatun ƙasa don samar da taki mai yawa; ana amfani da shi sosai a cikin shinkafa, alkama, masara, dawa, auduga, 'ya'yan itatuwa, kayan marmari da sauran kayan abinci na abinci da amfanin gona na tattalin arziki; ana amfani da shi sosai a cikin ƙasa ja da ƙasa rawaya, ƙasa Brown, ƙasa mai ruwan hoda-fluvo-mai ruwa, ƙasa baƙar fata, ƙasa kirfa, ƙasa shuɗi, ƙasan albic da sauran halayen ƙasa.
A yi amfani da hanyar sinadarai na gargajiya (Hanyar Den) don samarwa.
Phosphate dutse foda (slurry) yana amsawa tare da sulfuric acid don rabuwa da ruwa mai ƙarfi don samun rigar-tsari mai tsarma phosphoric acid. Bayan maida hankali, ana samun phosphoric acid mai maida hankali. An haɗu da phosphoric acid da phosphate dutse foda (wanda aka kirkira ta hanyar sinadarai), kuma ana tattara kayan amsawa kuma suna balaga, granulated, bushe, sieved, (idan ya cancanta, fakitin anti-caking), da sanyaya don samun samfurin.
Superphosphate, wanda kuma aka sani da talakawa superphosphate, shine takin phosphate wanda aka shirya kai tsaye ta hanyar lalata dutsen phosphate tare da sulfuric acid. Babban abubuwan amfani sune calcium dihydrogen phosphate hydrate Ca (H2PO4) 2 · H2O da ƙaramin adadin phosphoric acid, da kuma calcium sulfate mai anhydrous (mai amfani ga ƙasa mai ƙarancin sulfur). Calcium superphosphate yana ƙunshe da 14% ~ 20% P2O5 mai inganci (80% ~ 95% wanda ke narkewa cikin ruwa), wanda nasa ne na takin phosphate mai narkewa mai sauri. Grey ko launin toka fari foda (ko barbashi) ana iya amfani dashi kai tsaye azaman taki phosphate. Hakanan za'a iya amfani da shi azaman sinadari don yin takin gargajiya.
Taki mara launi ko haske mai launin toka (ko foda). Solubility mafi yawansu suna da sauƙi a cikin ruwa, kuma kaɗan ba su narkewa a cikin ruwa kuma a sauƙaƙe a cikin 2% citric acid (citric acid solution).
