K'halsiamo phosphate

Tribasic acid e phosphoric diforomo le mefuta e meraro ea letsoai k'halsiamo. Sena k'halsiamo hydrogen phosphate CaHPO4, k'halsiamo dihydrogen phosphate Ca (H2PO4) 2 le orthophosphate, kapa k'halsiamo phosphate, eo moralo e ileng ea fanoa ke: Ca3 (PO4) 2. letsoai ena ke ntho inorganic, tlas'a maemo a tekanyetso ke o tiileng, 'me makhalo mokelikeli (qhibiliha) ka mocheso oa 1200 C. The segokanyipalo sa lekana le 2,81 g, / cm³, ho molare boima - 310,2 g, / mole. K'halsiamo phosphate ke hampe qhibilihang ka har'a metsing: ho 20 ° C le karoloana boima ba ha sa feteng 0,0025%. Ho fapana le metsoako e meng ka ho fetisisa, boemo ba solubility lona decreases le eketseha mocheso. Kahoo, ka futhumatsang letsoai ena ke khona ho theha mobung.

K'halsiamo phosphate ke tšoeu bonaletsang ntho eo ke karolo ea liminerale apatite (ke oa sehlopha sa phosphates nang ho fihlela ho 56% Cao le ka 41% P2O5), phosphorite (fibrous kapa teteaneng phutheho ea apatite nang fetang 18% P2O5) le hydroxyapatite (ka sehloohong motsoako oa lesapo batho le liphoofolo). Re bontša hore re ka tšimoloho ea ba bang mobung oa mantle kapa liphoofolo tse shoeleng. likarolong tse ling (mohlala, maoatleng ea boholo-holo) thehoa ka lebaka la bophelo ba "fosforobaktery". Empa libakeng tse ling, mobung ea matsoai ena ke hlahang ho yona feela matsoai. Kaofela ha bona ba abuoeng ka tlhaho 'me ba sebediswa ho moruo ea sechaba.

Apatite ke lintho tse bonahalang e tala bakeng sa phosphorus, phosphate manyolo le asiti phosphoric, hammoho le sebelisoa ka ferrous le nonferrous metallurgy ka tlhahiso ea khalase le ceramic. Natural liminerale ke phosphate mafika se hlahang ho yona fapaneng, empa ho feta sedimentary, ba sebediswa bakeng sa ho matlafatso ho eketsehileng 'me ho hlahisa manyolo phosphate. Metšoasong phosphorites le apatites ke ea bohlokoa haholo ho temo, kaha ha feela sebelisoa ho hlahisa manyolo, empa hape e le e-ba mohloli k'halsiamo bakeng sa linonyana kapa liphoofolo tse fepa: furu k'halsiamo phosphate hlahisitseng ho latela GOST 23999-80.

Matsoai inorganic - apatite - e sebelisoa ka dithulaganyo difeme fetang mashome a mabeli. tšebeliso ea eona e leng tlhahiso ea abrasives, khalase le letsopa, hammoho le bakeng sa ho hlahisa bolokolohi phosphoric acid e le phosphorus. Tsela tsoela ho ea ka leqheka la ho: 3SiO2 + Ca3 (PO4) 2 + 5C → 3CaSiO3 + 5CO + 2P. ntho ena e boetse e ile a bolela ho indasteri e ea lijo: fumaneha ka lijo tseloe E341 latela GOST P 53945-2010, moo, hammoho le 1- le 2-ka go engwa legatong letsoai ea acid e phosphoric kenyeletsa k'halsiamo phosphate. Oa ho lokisetsa sehlahisoa sena se akarelletsa ditlhoko stringent bakeng feedstock ena. Ka ho hlahisa ho sebelisoe lijo sebelisa acid e phosphoric sehlopheng A ho latela GOST 10678-76, k'halsiamo hydroxide latela GOST 9262-77 le lik'hemik'hale tseko tjhoko latela GOST 8253-79.

Matsoai nang k'halsiamo phosphate, o phetha karolo ea bohlokoa ho 'mele oa motho. Hydroxyapatite ka emeloa ke moralo 3Sa3 (PO4) 3 • Ca (OH) 2. Ke karolo e ka sehloohong ea lintho tse bonahalang tsa ho haha le lesapo batho. Sena se phetha karolo ea matsoai ea enamel ka mokgwa fluorapatite. Tlhokahalo ea letsatsi le letsatsi bakeng sa kgolo le phosphorus ka mefuta e fapaneng ho tloha 800 ho 1500, mg. Nakong ea metabolism tsa metsoako phosphorus ka 'mele oa motho o arabela sebete le ho laola mokhoa ona li-hormone le vithamine D. mafu Various ba lesapo le meno ntshetswa pele le khaello ea phosphorus' meleng. k'halsiamo phosphate tlisoang ke ho lijo, matlafatsa meno le masapo, 'me hammoho le liminerale tse ling tshehetsa tsamaiso la pelo, ho thibela kankere matshwao mala, laola methapo ea kutlo mosebetsi, ho akarelletsa le ho haha collagen, thusa tlaase k'holeseterole e. The phosphates tse tswang mantle, 'me moroto letsatsi lokolloa ka 4 g, ya letsoai phosphoric acid e.
