Dhulka Faytamiin-Naadirka Warshadaha Casriga ah

Dhul naadir ahwaa magac wadareed oo ka kooban 17 walxood oo macdan ah, oo loo yaqaan "fitamiin warshadaha casriga ah", waa kheyraadka macdanta istiraatiijiga ah ee muhiimka ah ee Shiinaha, ayaa si weyn loogu isticmaalay difaaca qaranka, hawada hawada, agabka gaarka ah, birta, tamarta iyo beeraha iyo meelo kale oo badan.Shiinaha waa dalka ugu weyn ee kaydka dhulka naadirka ah iyo dalka wax soo saarka, kaas oo magaalada Baotou ee gudaha ismaamulka Mongolia ay leedahay 83.7% kaydka qaranka, 37.8% kaydka caalamiga ah, macdanta Bayan Obo waa macdanta ugu wayn aduunka ee naadirka ah.

Biraha dhulka naadirka ah iyo Alloys ay ka ciyaaraan deoxidation iyo desulphurization door in steelmaking, taas oo hoos u dhigi kartaa content ee labada in ka yar 0.001%, beddelo qaabka inclusions, sifeeyo hadhuudh, si loo hagaajiyo waxqabadka processing ee birta, hagaajinta xoogga. adkaanta, caabbinta daxalka iyo caabbinta oksaydhka.Biraha dhulka naadirka ah iyo alwaaxdooda waxaa loo isticmaalaa soo saarista birta kabka nodular, birta cawl xoog badan iyo kabka vermicular, taas oo bedeli karta qaabka garaafka ee birta shubka, wanaajiso habka shubista, iyo hagaajinta sifooyinka farsamada ee kabka. birta (birta alloy, birta la shubay).

Budada dhalaalaysa ee dhifka ah ayaa loo isticmaalaa in lagu nadiifiyo aaladaha galaaska ee kala duwan, CeO2 waxaa loo isticmaalaa in lagu midabeeyo muraayadda oo loo hagaajiyo daahfurnaanteeda.Pr6O11, Nd2O3, iwm, loo isticmaalo midabaynta dhalada;La2O3, Nd2O3, CeO2, iwm ayaa loo isticmaalaa samaynta dhalo gaar ah;Warshadaha dhoobada, dhulyo naadir ah ayaa loo isticmaali karaa in lagu sameeyo dhaldhalaalka dhoobada ah, refractories iyo alaabta dhoobada.Nadiifinta sare ee dhifka ah ee dhulka sida Y2O3, Eu2O3, Gd2O3, La2O3, Tb4O7 waxaa loo isticmaalaa in lagu soo saaro noocyo kala duwan oo walxo fluorescent ah, sida fosfoor cas TV midabka, fosfoor cad oo TV ah, fosfoor gaaban oo gaaban, fosfoor kala duwan oo iftiin ah, X- phosphor shaashadda kor loo qaaday iyo iftiinka iftiinka walxaha fluorescent.

Biraha dhulka naadirka ah waa qayb muhiim ah oo ka mid ah qalabka casriga ah ee casriga ah.Taxane semiconductors ah oo isku dhafan, walxo koronto-optical ah, alloys gaar ah, qalab cusub oo shaqeynaya iyo xeryahooda organometallic oo ka kooban biraha dhulka naadirka ah iyo biraha aan birta ahayn waxay u baahan yihiin biraha dhulka naadir ah oo leh astaamo gaar ah.Qadarku waa yar yahay, laakiin waa muhiim.Sidaa darteed, waxaa si weyn loogu isticmaalaa teknoolajiyada isgaarsiinta casriga ah, kombiyuutarada elektarooniga ah, horumarinta hawada, daawada iyo caafimaadka, qalabka sawir-qaadista, qalabka korantada, qalabka tamarta iyo qalabka kicinta.Shiinaha ayaa qani ku ah macdanta birta ah ee dhifka ah, taas oo bixisa xaalado kheyraad oo wanaagsan horumarinta warshadaha birta ah ee dhifka ah.
