Rare pasiizita remubatanidzwa we 17 esimbi zvinhu, inozivikanwa se "yemazuva ano maindasitiri vhitamini", chinhu chakakosha chicherwa chekushandisa muChina, chave chichishandiswa zvakanyanya mukudzivirira kwenyika, muchadenga, zvinhu zvakakosha, simbi, simba uye kurima uye nezvimwe zvakawanda minda.China ndiyo inyika yakakura kwazvo isingawanzo kuchengeterwa pasi uye nyika yekugadzira, iyo Baotou guta riri muInner Mongolia inozvitonga Dunhu ine 83.7% yenzvimbo dzakachengetwa, 37.8% yenzvimbo dzepasirese, Bayan Obo mine ndiyo yakakura kwazvo pasirese mugodhi wepasi.
Rare pasi simbi uye alloys adzo anoita deoxidation uye desulphurization basa mukugadzira simbi, izvo zvinogona kuderedza zviri zviviri kusvika pasi pe0.001%, shandura chimiro chemukati, kunatsa zviyo, kuitira kuvandudza mashandiro esimbi, kuvandudza simba, kuoma, kusimba kwekusagadzikana uye oxidation kuramba.Rare ivhu simbi uye alloys ayo anoshandiswa mukugadzira nodular cast iron, yakakwirira-simba grey cast iron uye vermicular cast iron, iyo inogona kushandura chimiro chegraphite musimbi yakakandwa, kunatsiridza maitiro ekukanda, uye kunatsiridza mashandiro emakanika. simbi (alloy steel, cast iron).
Rare ivhu rekuporisha poda rinoshandiswa kukwenenzvera akasiyana magirazi magirazi, CeO2 inoshandiswa kusvibisa girazi nekuvandudza kujeka kwayo.Pr6O11, Nd2O3, nezvimwewo, inoshandiswa kugadzira girazi;La2O3, Nd2O3, CeO2, nezvimwewo zvinoshandiswa mukugadzirwa kwegirazi rinokosha;Muindasitiri yeceramic, mavhu asingawanzo anogona kushandiswa kugadzira ceramic glazes, refractories uye ceramic zvinhu.Single yakakwirira kuchena isingawanzo oxide epasi seY2O3, Eu2O3, Gd2O3, La2O3, Tb4O7 anoshandiswa kugadzira akasiyana emhando yefluorescent zvinhu, seruvara TV tsvuku phosphor, fungidziro yeTV chena phosphor, yekupedzisira pfupi kutsungirira phosphor, akasiyana mwenje phosphor, X-. ray yakawedzera skrini phosphor uye chiedza chekushandura fluorescent zvinhu.
Rare earth metals chikamu chakakosha chemazuva ano chepamusoro-tech zvinhu zvitsva.Mutsara wemakomboni semiconductors, electro-optical materials, special alloys, new functional materials and organometallic compounds inoumbwa neare earth metals and non-ferrous metals inoda simbi isingawanzoitiki ine zvinhu zvakasiyana.Mari yacho idiki, asi yakakosha.Naizvozvo, inoshandiswa zvakanyanya mune yemazuva ano yekutaurirana tekinoroji, emagetsi makomputa, kusimudzira aerospace, mushonga uye hutano, photosensitive zvinhu, photoelectric zvinhu, simba zvinhu uye catalyst zvinhu.China yakapfuma mune zvisingawanzo pasi simbi zvicherwa, izvo zvinopa zviri nani zviwanikwa zvekusimudzira indasitiri yesimbi yepasi isingawanzo.
