4. Kaydka iyo Qaybinta
(1) Kaydka: Kaydka caalamiga ah eelanthanum cerium biraha daawahaaad bay u badan yihiin, inta badan waxaa lagu qaybiyaa saldhigyada kheyraadka dhulka naadir ee Shiinaha.
(2). Qaybinta: Shiinaha ka sokow,lanthanum cerium biraha daawahaWaxa kale oo lagu qaybiyaa wadamo ay ka mid yihiin Mongolia, Maraykanka, iyo Australia.
5, Qiimaha iyo Suuqa
(1). Qiimaha: Qiimahalanthanum cerium birta daawahawaxaa saameeya saadka iyo baahida suuqa, kharashaadka wax soo saarka, iyo arrimo kale, taasoo keentay isbedbedelka qiimaha.
(2). Suuqa: Suuqa caalamiga ah eelanthanum cerium biraha daawahawaxay inta badan ku urursan tahay dalka Shiinaha, oo ah dalka ugu badan ee wax soo saarka iyo dhoofinta dhulalka dhifka ah.
6. Hababka iyo hababka diyaarinta
(1). Hababka diyaarinta: Hababka ugu muhiimsan ee diyaarintalanthanum cerium biraha daawahawaxaa ka mid ah isku dhafka kiimikada iyo hababka jireed. Habka isku-dhafka kiimikaadku waa in la diyaariyo isku-dhisyada dhulka naadir ah iyada oo loo marayo fal-celin kiimikaad, ka dibna laga helo biraha iyada oo loo marayo dhalaalid heerkul sare ah; Sharciyada jireed waxaa ka mid ah electrolysis, dhalaalidda gobolka, iyo wixii la mid ah.
