Ngwakọta nke lanthanum carbonate

Lanthanum carbonatebụ ihe dị mkpa kemịkalụ mejupụtaralanthanum, carbon, na oxygen ihe. 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.
