Ngwakọta nke lanthanum carbonate
Lanthanum carbonatebụ ihe dị mkpa kemịkalụ mejupụtaralanthanum, carbon, na oxygen ọcha. Usoro kemịkalụ ya bụ La2 (CO3) 3, ebe La na-anọchite anya elementrị lanthanum na CO3 na-anọchi anya ion carbonate.Lanthanum carbonatebụ kristal na-acha ọcha siri ike nke nwere ezigbo okpomọkụ na nkwụsi ike nke kemịkal.
Enwere ụzọ dị iche iche maka ịkwadebe carbonate lanthanum.Ụzọ a na-emekarị bụ imeghachi omumelanthanum metalna itughari nitric acid iji nweta lanthanum nitrate, nke a na-emeghachi omume na sodium carbonate iji mepụta.lanthanum carbonateigbanye. Na mgbakwunye,lanthanum carbonateEnwere ike nweta ya site na iji lanthanum chloride meghachi omume sodium carbonate.
Lanthanum carbonate nwere ngwa dị mkpa dị iche iche.Nke mbụ,lanthanum carbonateenwere ike iji ya dị ka akụrụngwa dị mkpa maka ọla lanthanide.Lanthanumbụ aobere ụwa metalnwere mkpa magnetik, ngwa anya na electrochemical, nke a na-ejikarị eme ihe n'ọhịa dị ka ngwá electronic, optoelectronics, catalysis, na metallurgy.Lanthanum carbonate, dị ka ihe dị mkpa precursor nke lanthanide ọla, nwere ike inye a isi ihe maka ngwa na ndị a ubi.
Lanthanum carbonatenwekwara ike iji kwadebe ogige ndị ọzọ. Dị ka ihe atụ, imeghachi omumelanthanum carbonatena sulfuric acid na-emepụta lanthanum sulfate nwere ike iji kwadebe catalysts, ihe batrị, wdg.lanthanum carbonatena ammonium nitrate na-emepụta ammonium nitrate nkelanthanum, nke enwere ike iji kwadebe lanthanide metal oxides,lanthanum oxide, wdg.
Lanthanum carbonatenwekwara uru ngwa ọgwụ ụfọdụ. Nnyocha egosila nalanthanum carbonateEnwere ike iji ọgwụgwọ hyperphosphatemia. Hyperphosphatemia bụ ọrịa akụrụ a na-ahụkarị, yana mmụba nke ọkwa phosphorus n'ime ọbara.Lanthanum carbonatenwere ike ijikọ na phosphorus na nri na-emepụta ihe ndị na-adịghị edozi, si otú ahụ na-ebelata absorption nke phosphorus na ntinye nke phosphorus n'ime ọbara, na-arụ ọrụ ọgwụgwọ.
Lanthanum carbonatenwekwara ike iji kwadebe ihe seramiiki. N'ihi nkwụsi ike nke thermal na kemịkalụ dị mma.lanthanum carbonatenwere ike imeziwanye ike, isi ike, na iyi nguzogide nke ihe seramiiki. Ya mere, na ụlọ ọrụ seramiiki,lanthanum carbonatea na-ejikarị akwadebe ihe ndị dị ka ceramik okpomọkụ dị elu, seramiki eletrọnịkị, ceramik anya, wdg.
Lanthanum carbonatenwekwara ike iji maka nchekwa gburugburu ebe obibi. N'ihi ike adsorption ya na ọrụ catalytic,lanthanum carbonateenwere ike iji ya na teknụzụ ọgwụgwọ gburugburu ebe obibi dị ka ọgwụgwọ mmiri mkpofu na nchacha gas. Dị ka ihe atụ, site n'imeghachi omumelanthanum carbonatena ion metal dị arọ na mmiri mkpofu iji mepụta ihe na-adịghị edozi, a na-enweta ihe mgbaru ọsọ nke iwepụ ọla dị arọ.
Lanthanum carbonatebụ ihe dị mkpa kemịkalụ nwere nnukwu uru ngwa. Ọ bụghị naanị ngwa ngwa dị mkpa maka ọla lanthanide, mana enwere ike iji ya na nkwadebe nke ogige ndị ọzọ, ọgwụgwọ hyperphosphatemia, nkwadebe nke ihe seramiiki, na nchekwa gburugburu ebe obibi. Na-aga n'ihu mmepe nke sayensị na nkà na ụzụ, ngwa atụmanya nkelanthanum carbonatega-adịkwa obosara karị.
